At times this project was fun, and other times it was hell. Ultimately, by building on the fantastic work of others, we have an emulated Spacemouse that can be made for $20 of parts, thanks to Arduino and 3D printing. My version is a little bigger than I expected, so maybe a V2 is on the cards.
Thanks to Shiura and all of the other contributors to this great project.

V1 has been dubbed 'Bigfoot' on Printables. V2 is now out, which I have called 'Mini-ish''. It's much, much smaller and has some code tweaks to require a smaller range of input motion. Same link as before: www.printables.com/model/864950-open-source-spacemouse-space-mushroom-remix
Dang V2, came out right as I finished V1 almost on the dot. :)
already printing them out 😎
Love it. ❤️ I'll wait a couple of weeks before making this in case a V3 comes out. 😃
@@johncrombie2771 dude... build the v2 and then use it in cad to iterate the v3! then take a pic of you working on the model of v2 while using the actual physical v2... meta. lmfao. but seriously... thats what makes open source stuff like this awesome
i had actually spent some time trying to 3d scan a big chunk of play dough i made into an ergonomic wrist/palm rest for my space mouse. those files are around somewhere too... rests for the smaller 3dconnexion one as well.
There is a project VjoySerialFeeder that can take anything you can possibly connect to an arduino into a joystick in windows and linux, i already implemented a lot more stuff and i'll upstream until the end of the week. For instance, support for playstation 2 controllers and key matrices, i wanaa play racing games with my gameshark pedal and the ps2 controller, the software seems good but my arduino forgot it's bootloader and i need another one. I will probably be implementing support for other controllers as well.
I see you turned the joystick PCB's sideways (which is what my design is using so I can reduce the height of the unit)...did you have to do any reversal of variable directions or just switch the X and Y connections?
I haven't gotten to debugging yet so I don't know if more than connector swapping will be necessary...
Dude, you should call it the Space Capybara, because that is the largest computer rodent I've ever seen 🤣
Great project though, looking forward to making (hopefully a much smaller) one 😁
Thanks for all the work you, and everyone else have put into it so far.
THIS. What a good name lol.
'Stellar Capybara' for extra knockoff vibes.
@@MumrikDK Nice :D
@@MumrikDK This is the correct name. :D
What about the "Capynaut"?
Super neat, would like to see a smaller version.
Right, that thing is huge.
Yes me too!
I think it's cause the internal components in that version are rather big. You would have to go with one of the different more complex models he showed at the start. Or buying one of the 3d connexion ones, they are quite small. I've had one for around 10 years, still works.
That size is good for more precise movement, in small joystick 🕹 even a little fingers shake of 1 mm can make a huge difference
@@atnfn It's such a shame the 3dconnexxion wireless versions still use Micro-USB
...using Hall effect sensors instead of the joysticks and some springs to hold the dome will greatly reduce the size.
There is already such a project for at least half a year, I even have replicated it myself. They both just frustrating rubbish compared to commercial product, unfortunately.
IMHO hall effect Should be where the open source community should concentrate their efforts.
Printed compliant mechanism too.
I own one already......😄
@@missassembly It's also where the big companies should concentrate as well. Hell, Microsoft already uses Hall effect sensors in their Xbox One (and newer) controllers. They just don't use them in their joysticks. Their triggers use them
@@vadimsham8047What's the name of the project, and what were the issues?
When building my "space mouse", the biggest issue is that it can only send mouse actions, rather than communicate directly with the CAD software. The idea that mimic a SpaceMouse to use the driver is very interesting.
It's folly, it'll never be as good. This video is filler.
@@mayamanign nobody says it would be better then the original. But 20-30 bucks is a lot more justifiable then 300 for most hobby makers. So, not filler but maybe not for you
@@robinpopkema I will make this for sure. I use 3 different slicers for FDM (Prusa, Qidi, Orca), Lychee and Voxeldance tango for resin, fusion 360 and rhino for modelling and blender for sculpting. A colleague of mine had lent me a spacemouse which works with all of these and all use the same settings. But without a space mouse, I have to know which software uses which dumb shortcuts. Is shift needed for zoom? Was it control? Control + right click? It drives me nuts. Especially as I tend to jump from machine to machine as my work machine is windows, my home machine is Mac and I also have a linux desktop for some tasks. (KVM switch rules) So if this achieves the simple point that I can have the same exact navigation in ALL my software without tinkering endlessly with settings, it is an extreme win in my book. If I install the 3dconnexions software and I do not have to individually set up my softwares on all the platforms and machines, I'd be so so so sooo happy.
The OG spacemouse is extremely overpriced for what it is. I know it took time to develop - check the cut up video how it works.
Most other already existing solutions were simply too complicated. So I am all for this! Gigantic KUDO from me. I am already collecting the parts from local distributors to be able to make it.
@@mayamanign so the $20 device wont be quite as good as the $300 device?
Oh noooooo
what exactly cant it do?
@@ge2719 This DIY version is missing 2 programmable side buttons. Looking at the wiring diagram, it seems like there might be capability to wire in 2-9 buttons to Arduino pins (I haven't used Arduino in a while so unsure of the difficulty of using the I2C, serial, and SPI pins for GPIO).
I bit the bullet and bought a space mouse. I love it. I use a lot of CAD sometimes 8 hours a day and see it as a worth while expense. I'm so glad 3D printing can make it more accessible to the hobby market.
Yeh.. they are SOO brilliant once you get the hang of it and the right driver set up. It's like getting another arm or something.
I'm hoping this will lead to better software integration for space mice. Kinda sucks that they can only be used for a couple programs right now.
Space mouse let's me do things so much fricken faster it's not funny. If you're doing CAD full time there's no reason not to plop down that money. It's your tools of the trade, don't skimp!
I find people don't put enough thought in their normal mouse selection either. I'm a trackball guy though I wish I could find on with even more programmable buttons. 8 isn't enough, lol.
@@sirrodneyffing1 really its like getting 2 extra arms with another mouse for each. Mice only have 2 DOF, space mice have 6.
@@louisbrill891 The rare stacks of CAD applictions with a spaceouse driver mate. Even Freecad (still needs work), Unreal Engine and Blender's is really good now from wobbly start.
I bought a used SpaceMouse Pro on ebay for $120. It was WELL worth the price!! I absolutely love this thing for 3d modeling.
without a deadzone option, the device, whenever i take my hand off one of these devices, the viewport/camera in any cad software is sent miles away which is really frustrating. For 15 years people have been asking for this option but it only exists as a driver hack and it's pretty janky - i cannot see how it's not a scam after testing multiple devices on multiple computers and always getting the same result.
@@TheExileFox I had an old Space Pilot Pro, and he started to move alone, I fixed it my editing the settings file to make a deadzone, so no more self drift or self rotation of the object.
Since work like a charm
I just switched to the SpaceMouse Enterprise, just because i wanted to spend some money :p
Weird, mine has never moved when my hand is off of it. Maybe I just got lucky and got a good one
He's in Australia, so it's many more dollars in their currency.
Bought my regular spacemouse used for 60USD, absolutely worth it, but nice to finally see some alternatives.
The reason the mushroom/control knob is so large is that it holds the 4 joysticks. The simplest way I think to reduce its size is to move them to the outside with their control sticks pointing inward. Yes, it would require a redesign of the 3d printed parts but should be lest bulky looking.
Could also use joycon-style joysticks, e.g. the hall-effect ones from gulikit to get them smaller while still using off-the-shelf hardware.
Had the same thought. There's likely a way to use hall effect sensors to do this but I'm not super well versed in electronics and part of the appeal here is off the shelf parts. One of my first thoughts was PSP /3DS style thumb-slide joysticks. They're very small and only a few dollars each
Better would be to redesign it to not use potentiometer based joysticks and instead to use some form of hall effect sensor. You get some that can apparently work as 3D joysticks.
Worked running Autodesk Inventor everyday.. I cannot understate just how useful these are. With enough use, they pay for themselves by the amount of time saved when navigating around a model/assembly. Cool to see w good diy version..but there is a reason why the 3dconnection ones are so popular
I just realised you could make the knob quite a lot smaller simply by mirroring the four joysticks, so they sit on the outside of the knob instead of inside. The base would still be much the same size of course, but the knob would be more like the genuine Spacemouse type.
This is how he made the mini v2)
Fantastic!
I own an actual spacemouse but will build this just for fun and as a tribute to your skill and generosity!
I very much enjoy all your vids. Definitely one of the top channels.
All the best from Buenos Aires, Argentina
WOW! Ultra Hats Off for your hard work to pull everything together! Specially the space mouse section. That is the game changer!
As usual excellent content!!!
Thanks Michael!!! I'll keep an eye for the smaller version, but this is an amazing tool!! Thank you and the rest of the community for sharing!!
Heroic Effort! Thanks for sharing your work with us!
That’s a crazy amount of work for a video. Kudos
What a cool project! I’ve been interested in a space mouse too but this is the way I’m going to go. Thank you for sharing and to all who contributed!
Definitely enjoyed this video. I started watching this channel due to the 3d printing focus, but I do enjoy the expansion into the use of arduino and merging it with 3d printing as well. Looking forward to future electronics videos as well as the smaller version of the space mouse.
As someone in the market for a space mouse, this video is great. I'm going to be ordering parts and doing the build in the next week or so.
While watching the video though, it strikes me that the solution to the overall size could be as simple as reducing the size of the big joystick's actually manipulated surface area. Instead of mimicking the shape of the 3dconnexion joystick, you could make it look a lot more like the smaller joystick nubs. Bring the whole shape to a more rounded dome, then give it a stem and a wide head. That way, instead of pressing down on the front of the joystick, you can lift up on the back to get the same angle. Could probably even do it with your thumb. The shroud the whole joystick sits in can also be raised to cover all but the moveable range so your fingers can rest on it and then move the stick with about twice as many controllable angles. I'll be testing this once I've got the base build assembled, but if anyone is further along with it and wants to give it a go, I could mock up a model to reference.
Awesome project & tutorial. I’ve been looking for this type of mouse, gonna give your a go. Thanks for sharing.
Nice project! I absolutely love my Space Mouse but it was quite expensive (even the cheapest version). Now it is accessible to many more people. I hope the community will keep improving this.
This is a great project I would definitely take on myself for home use. I have a dedicated Space Mouse for my mechanical engineering job I use daily for 10 years now and love using it. Being able to diy one myself for home is a great option. Thanks for posting this!
95% of joysticks on Amaz/Aliex are stiff + have worthless "potentiometers", including the ones in the vid. That ends up making them digital devices, as shown with his CAD movement at 5:50. Even ones that claim to be OEM are nearly all fakes. The only good option is to salvage from old controllers or buy from a seller I finally found called "SOSS Gaming", but you'll need to solder them to PCB's yourself.
No point making a 6DoF device if it's not analog.
Love how hours (days?) of troubleshooting get compressed into a sentence 😅. Thanks for the great work.
Thank you for the work you put into providing this for the community my guy. I don't even need one of these things and now I want to make one. Thank you again for the project.
Well, damn....there went my weekend, lol! Thanks Mike! Great collaboration and development!
Thank you Michael, i tried the original project in the past but abandoned it cause i encountered the same weird problems and didn't want to bang my head against the math involved in the transformation matrix. I'm very happy to see the project has been carried over and perfetioned. I'll give it another shot thanks to you. Thank you again!
Bought mine for 60 usd, really happy with it. Awesome job on the DIY version!
Wish you hit 300K with this complete tutorial. Thank you so much. You don't steal your channel name at all, it's actually about "teaching tech" the best way I came across on youtube. But overall your great job is an hymn to collective intelligence. You deserve a way greater audience. As helpful as instructive with a lot of useful details. Aussies are really tech savvy. Congrats! I'm going to make that spacemouse. Have a great weekend my friend.
Dope. Lots of love from the PNW
I love your projects! Great job!
Company got me a Space Mouse Pro about 15 years ago and once you start modelling with it you will never go back to mouse only.The experience is so good I got myself one for home use.
Absolutely amazing! Thanks a lot, Michael! - Gone printing.
I bought a SpaceMouse Pro, used many years ago. It is really a great tool, and I only design practical stuff for home projects.
I think it is a lot of value, and the extra buttons on the pro version, I do use a lot.
Great video and project! I've long thought about building a custom mouse that fits my hand perfectly, but this is even more useful.
For those of you with weird complaints about this video; this isn't a competitor to Space Mouse at all. More like a hobby project. It's not worth the time to build one yourself, more like a fun project to challenge yourself to learn and build new things.
That said, this project is exactly what this channel is about. Teaching Tech.
This is amazing, another level of engineering.
Awesome instructions, it helps GREATLY when problems are left in the videos... I ALWAYS seem to get frustrated by little bugs I come across while following instructions- troubleshooting tips are always valuable!!!
Wicked! Can't wait to build one, thanks for sharing.
Heck yeah … finally a way to find out if it’s going to be. Useful addition, fantastic work.
Even at that size, I would be tempted to give it a try. I switched to using a trackball a few years ago, and I've seen pictures of space mice but never have tried using one.
Yay, I was on a 2 year journey too to make pretty much the same. I tried joysticks, I tried IMU's, I settled on halleffect sensors and some magnet.
Mine is a bit more 'delux' with a 2.8" touch screen, round display in the center of the dial, encoder in the dial for scrolling.
The software was the far most time consuming! I ended up designing a web wizard to configure all the touch buttons and other functions.
I based mine on an ESP32, since it needs to house a webserver, beside Bluetooth, MQTT and drive the 2 displays.
Oh and then I made the giant version with 3 touch screens....
Great project! I looked into making a DIY space mouse before but with all the existing projets there was always something that seemed "too hard" or "too difficult" for me to emulate. Your project absolutely nailed it though, and now it seems so much more achievable. Massive thanks for documenting all your progress and putting a guide together, I'll definitely be making one of these! :D
Just buy the spacemouse, omw its so worth the money for the compatability with multiple software, it lasts a very long time, my enterprise model is 6+years old and still works perfectly. One of the best purchases i made for my hobby, before it now became my career. I cannot stress enough, if you enjoy 3d modelling it will bring joy to your life.
This is amazing! I know what my next project is going to be!!
Big props for making it work. After seeing how much you had to put into getting it to work I don't regret buying a used SpaceExplorer on eBay. Only issue I've had is I'm stuck on an old version of the software since 3DConnexion no longer supports the older models. It's a really cool input device but I keep forgetting it's there and just manipulating things the way I'm used to with my mouse.
This looked very interesting - thank you for sharing
I love the comically large size! I also have been down this road. I suspect there is a pretty comprehensive patent on this since there aren't even Chinese knock-offs on Aliexpress.
that is a very interesting point, which now has me searching......today's new rabbit hole
There are a few versions out there, at least one of them is bound to be based off old patents from some earlier model. Not sure if the eddy current one or another one not mentioned in this video, that uses semi transparent ramps and LED / phototransistor pairs. There's also another really cool one that looks a bit difficult to make and uses load cells and a rig that looks like a motion platform.
This one in the video looks by far the easier one to make, every other one will require a custom PCB, some precision parts that will likely only work if printed on resin and some electronics that, if you're unlucky to live in a country like mine with ridiculously high import taxes, where most stores only send stuff through an expensive courier service, will cost you about the same as an entry level space mouse, if not more than that.
If I hadn't bought my space mouse I'd be ordering the parts right now. Still might build one if I get caught up on my current projects. Also, did the survey, hope it helps Michael. Thanks for the great video!
This is a kind of pretty dense tutorial you'd better watch more than once. At least what I'm doing ;) A GREAT GREAT JOB indeed. Combining several technical sources (and debugging or improving some of them) is all but easy. Michael made it happen in a brilliant and MASSIVE WORK😉Thanks a lot Michael!
Me thinking this is a small thing...bro thats huuuugee! I appreciate all the work you have done!
This is great! My new job has a 3Dconnexion and I really like using it but didn't want to spend the cash for my own. I looked into the 3D printed solutions but none seemed that great to me, especially since I didn't want it just using mouse / keyboard inputs, so knowing there's a way to emulate the 3dconnexion driver is really useful!
Edit: I also have 4 leftover tiny joysticks from repairing my Valve Index controller that I think I could shrink the design down by using, I feel a project coming on!
What a night, great videos from Michael and Marius hornberger within a couple of hours
Great content! Added to my build list!
I was lucky, i found a old 3DConnexion SpaceExplorer used for cheap, still works as new.
There are plenty, it's the best solution
I saw the one you started your work off of on hackaday, and with the semester ending, I was actually about to start working on making one. So this video is perfectly timed for me!
This is something that I am very interested in doing! Thank you!
YESSS!! Making it this weekend 🤩
Bless you, Michael! I tried and failed with the Orbion. The keyboard and mouse simulation did not play well with my setup either and was a show-stopper. The 3DConnexion firmware emulation alone has renewed my interest in making one of these.
Wow. What an ambitious project.
Easy way to make smaller means placing game controller module on the outside. Would leave a large base.
I bought mine used in nearly new shape for like 150 euro's. Awesome piece of kit.
Very impressive work!
i love it! once you go 3D Mouse, you never go back
exactly, last month I wanted to demonstrate a project on my F360 on my laptop , but 100% of time I desin on my home computer, The customer think I was a beginner because on the laptop I don't even know now how to turn an object without my SPaceMouse Enterprise :p (and before Space Pilot Pro, but after 5 years he began to move alone)
@@xTreme.Power. that's a tricky situation, that had happened to me also. I try to not use it from time to time so i don't forget how to orbit or make camera movements on different 3D software
I have a Space Mouse with a Stream Deck placed in a 3d printed base. It works great and the Space Mouse is a game changer for Shapr3D.
Love the diy version. I bought a 3D mouse after using one at work. I highly recommend it for anyone doing CAD / Blender even works in most slicers. I'm surprised they are not more popular with cheper alternatives.
Well done! I'm shocked that official Spacemouse prices have skyrocketed so much. I think I paid $99 CAD for my original, and even less for a used one. More importantly I'm glad I'm not SOL if the company ever goes under, thanks to everyone's efforts.
Just as a heads-up: the prices in the video are Australian dollars, so the numbers you see are a good bit bigger than you may be used to, but still, the prices for those things ARE steadily going up, with mostly the same unfixed **ahem** quirks as in the first models...
And it is the Australian importer / official reseller at that, not a straight USD/AUD conversion.
The least expensive one can be had in the US for $99 and I got a wired pro (I hate replacing batteries) for less than $200 on sale.
I’m definitely thinking about trying this. I’ve been looking at the space mouse for awhile.
I use solidworks professionally and use a space mouse. I will never go back without one. I may make this for at home. Thanks for the video.
Amazing content as usual 💪✨
Impeccable timing man yesterday i was just looking getting one but as u said too damn expensive
Super cool project!
I am so excited to build this!
I'm already printing out the parts and I just ordered the joysticks and microprocessor.
Very impressive and very helpful!
Another option for a cheaper 3D mouse is to look for some of the old, pre-USB units which are quite cheap on eBay. I'm not sure what hardware and software you need to adapt one for modern PCs, though.
Another similar device which is even harder to get nowadays is an eight-dial dial box of the kind which used to be available for SGI and Sun workstations. Building one of those would be a relatively straightforward project but it might be just as useful to have.
For the sim hardcore, one big challenge would be a faithful-looking, working replica of the Apollo Translation Control, a 3D controller designed to be used with the 3D-joystick Apollo Rotation Control.
seems to work really well!
I want to build one myself, but then was to lasy, Grate you came Up with an great Design.
Amazing project. I didn't know the Space Mouse worked in Onshape as well, I always believed it didn't.
an idea would be to place the josticks around the mushroom and not inside, it would enable a smaller design
I would love to do this. I think maybe making the parts that go on the joysticks just the ball part without a shaft could reduce the finished size. And maybe make a shroud for the LED section that has a thin area that can be for translucent flexible materials to let the light through and then a couple areas on the edges to slot into the body and handle? This gives me a bunch of ideas, that's for sure.
Amazing!! I was looking at buying but couldn’t justify spending the cash. I will be making one shortly, thank you!!
holy s#!t he did it boys! thank you so much for solving the software end of this. clearly the community had come up with clever solutions for the hardware end of things but the software solutions were always lack luster or difficult to implement with 100% success. your contributions to the community are invaluable
Brilliant work.
OMG Thank you for this!
I'd absolutely love an updated version with hall effect sticks and smaller footprint. I think that would crush
I looked at making one but after trialing the real thing at tafe I ordered it then and there love the space mouse (basic Bluetooth one) its well designed and top notch.
Got excited seeing the thumbnail and then list my shit when you showed this comically large brick
Cool idea, i think there is enough interest for V2! I would suggest smaller hall effect sensors for the joystick and maybe integrated butons in the base for shortcuts.
Def going to give this a try.
I love this I am going to try and build it myself
amazing! I would recommend also a github repo with the code, BOM and possibly licenses! would be awesome community project
Great project just needs to be half the size.
Great video. Keep up the good work.
100% recommend just getting a real one if you can, used would be fine too. They're proper high quality makes them a joy to use.
Hi!! Awesome video! I will definately build my own!!
This is wild, i was thinkig thinking about doing something like this a couple weeks ago
Reminds me of the SpaceOrb360 I used in the 90's to play video games. Mostly Descent, because you needed 6 degrees of freedom in the game.
The spacemouse is totally worth the money, I got my wireless one used for less that £80
The space mouse wireless is pretty good. Very handy in fusion. Although I still at time use the mouse to control
What I found amazing is the weight of the thing - it is hefty!
Is it supported in FreeCAD and Blender under Linux?
Very nice made! I like how you positioned all the electronics! :)
I do have the spacemouse pro and it's easy to move multiple axis at once instead of using every axis individually like all the open source designs.. but at 1 point, I believe the open source versions will be better than the originals ;)
anything will be better than my experience with 3dconnexion - without a deadzone option, the device, whenever i take my hand off one of these devices, the viewport/camera in any cad software is sent miles away which is really frustrating. For 15 years people have been asking for this option but it only exists as a driver hack and it's pretty janky
Great video, so want to do this! I've been eyeing up those spacemeeses 😁 for ages but the cost is prohibitive... a mkII a bit smaller would be 👌
So love the generous sharing of knowledge by all involved 🙌😎
I just bought a space mouse compact as the only thing I do on my pc is designing things with sketchup or fusion 360.
It was pricey at 149 euro but it works amazing.
I'm in the process of doing something similar, using a 9 axis imu to track motion, and a rp2040 with tinyusb to emulate a spacemouse.
I already assembled the controller and wired it, now i just need to find the time and will to program everything XD
It's another one of those projects that I get bored of before I finish it.
that does not gonna work...I tried. First of all you'll need 2 IMUs, otherwise you'll have trouble just moving the entire mouse; and this is a mechanical pain. Then you cannot really use the magnetometer without recalibrate the soft and hard iron magnetic field each time you move your mouse just few centimeters. At the end it's not a good solution
@@SaverioPieri i was going to use a magnet stuck on the base as a reference. I know it's not easy, but I guess that something could be done is this is the kind of tracking that could be obtaioned:
watch?v=yqFfmwVufMo
The issue i'm envisioning is with tracking pan movement, because that can only be done with the magnetometer, but rotation and pan are not easy to tell apart when the only thing you have is some vectors from the imu.
Can I follow your progress anywhere? Sounds really interesting. Thanks.
@@Muz994 well, there are a lot of libraries implementing sonsors fusion (kalmann etc..). My biggest problem was the fact that earth mag field is very very small compared to other sources in my desk: speakers, psu, even BT devices. As far I can freeze the status, the hard iron calibration works (sort of), but simply rising the speakers volume create a mess..... At the end I gave up with this idea. I hope you'll find a working solution
@@Muz994 ah...you dont need to catch the pan: the pitch and roll vectors give you the pan vector, while you maintain the position. The problem is the elevation (push and pull)
It looks small and very practical.
