You should do a video on the assembly of this car. I want to print it, and it would be great to see all the parts laid out, all other parts needed, then the build. Thanks for sharing
You are right, unfortunately this project is closed and finished I no longer have my Tarmo3. But I will be making a tarmo4 video soon and for that I will make an assembly video
Something to try for improving part strength. Immerse the parts in acrylic floor polish then put the container of polish and parts into a pressure tank to force the polish throughout the part. Then remove the parts from the polish and use a vacuum pump on the pressure tank to pull out excess polish. To finish them, 'bake' the parts in a food dehydrator at low temp (around 80 to 80 F) to ensure the polish is dry. The vacuum step can be omitted but during the dehydrator step some liquid will flow out. You'll want some paper towels below, but not touching, the parts no matter what you do so that any polish that comes out doesn't drip onto the floor of the dehydrator. What acrylic floor polish? Future, which in the USA is now called Pledge Floor Gloss. When dry it's very water resistant. Ammonia will dissolve it. I've found it to stick quite well to PLA. I've used it as a sealer on PLA parts to smooth them up a bit for making silicone molds. Using air pressure to force the acrylic into all the little nooks and crannies should improve strength by filling the gaps and helping bond layers together better. But I've not tested this theory to see if this has such an effect on the strength.
hey i just wanted to say thanks for designing this i am currently printing the remaining parts for the first of 3 files and it really did not take nearly as long as i was expecting it to take so thanks
I was designing a 3D printed car too & my printer broke. Hot end issues. But I am glad to see you succeeded. Great Engineering work and keep refining your design because it is exceptionally GREAT but perfection is infinite.
That’s pretty impressive that you designed the whole thing and how well it drives and functions. I wish I was that good at drafting :) great job though!!! Gave your video a thumbs up!!!
Hi, I am designing something similar and I was wondering how you did the steering. like the part at the end of the two arms that hold the wheel on. I saw two bolts in the video but from that angle, it looked like the bolts would have to go through each other. I really can't wrap my head around how that would work. Plz, help.
The only reason I haven't done that yet is because of axial loading that it would cause--Also the gears don't really break its always the axles that break--But to make it quieter, as you mentioned, I didn't think of that--So I might give it a try because of that!
Hello, I have built my Prusa I3 3d printer, but I am not confident in using it.Am I right in understanding these are the steps I must follow to start my first 3D print: 1.calibrate bed (2mm distance from print Nozzle, with a piece of paper) 2. warm up bed and nozzle, bed 170 oC and nozzle 220 oC. 3.insert SD card with files to print. 4. Select print from the menus. Is this right? will the printer NOT start printing until it reaches 220 oC? I need help with this, any tips gratefully recieved. Rob
Brilliant, I have a 3d printer on order, a Prusa of ebay.Hopefully I will be printing some r/c stuff maybe a simple boat or plane to start, this looks complicated but I hope I could do it. About your car, why not print a nice canopy for it?
Because I am not good at that sort of designing. But other members of the community have done that. Check out the subreddit where people have designed mods for the car.
@@EngineeringNS Thanks for the reply. I have the whole car folded, but I have a problem with electronics ...... anywhere I found in the document board that you have on the transmission to which is connected servo. Do you have a link where to buy it?
Hi, thanks for sharing this. I printed and assembled all machine, I printed all gears but now I cannot finish it because of small differential conic gears at 3.40 in the video. You use a metallic gears, I printed these in ABS but not works so good, just tried by hand, no motor already mounted. Please, how do you get these gears ? Thanks
@@EngineeringNS Thanks for reply. Where please ??? I found it on Thingiverse. Only these conic gears are missing, I printed all the machine , even the cover like Porche Carrera.
Thanks! I also use gears that are made for a Traxxas diff--I've got the actual diff too, but don't want to use it. If you happen to want to know more about that part, there is a BOM on the Thingiverse page linked in the discription.
Do you have a parts list that needs to be purchased? Motor, springs, esc etc. I'm a drone guy so rc cars are new to me! It looks incredible, really great work.
Completely random question: I saw the Family Dollar in the video and reminded me of my old campus apartments at Wichita State. Any chance its the same place? LOL
@@EngineeringNS Lol! Anyway, great project. This is my first project and I’m planning to use a Raspberry Pi as a computer on board (then use XBox controller for controlling). I couldn’t see any info on the software and radio on your Reddit or the instructions manual. Am I missing something here?
It only uses simple plug'n'play RC car electronics. Unless you want to try something more complex, all I used was a basic receiver and transmitter meant for RC cars. There is a guy on the subreddit who did something similar to what you are wanting to do: www.reddit.com/r/EngineeringNS/comments/ih2jqt/got_springs_builds_done_but_with_all_of_the/?
Really good work. There always is room for improvement. You could try raising the extrusion-speed in the top layer for example. And you might want to try out Nylon, it's quite cheap and supposed to work with most printers whilst being more durable than PLA or ABS. Once again, really good work. I shall recommend you to my friend, ma man!
But do some research before buying anything, I had some bad erperiences there. Oh, and I'm currently playing with rubber Filaments, might be fun if you tried out printing wheels. TPU is quite easy to print and considerably more flexible than PLA whilst still being durable. And its cheap.
Hi sir very interesting project. Thank you for uploading and sharing your knowledge and design. Can you help me how to assemble your open front diff? Iam lost,
Sorry, it isn't likely that I'll finish that doc. Just don't have the time to work on it. I'd rather spend my limited time working on the next project. If you get stuck then shoot me a message on reddit or Instagram.
Well no. There is no code, the ESC allows you to adjust 'punch' but starting the car is the smallest issue with regard to torque. It's hard to explain but if you ever drive an RC car you will understand.
Uses about 1 spool of filement maybe a bit less. Parts are the real cost, but I don't know how much exactly, there is a BOM on Thingiverse with all the needed parts
One is locked and one is open. If you don't understand try looking up videos on RUclips it will explain the purpose of this. The open diff is recommended on the front, the rear can be either open or locked diff.
@@EngineeringNS What part should i use for the open rear diff ? there is only locked part in the drivetrain files. I have printed Front_Diff_Cup_-_Part_1 for it but not assembled yet. Will they work or not? Thanks for your attention to comments btw.
There is a set of gears in the BOM file you must purchase for the open diff. You can see these gears at the end of the video there is a clip of me assembling an open diff.
Thank you! 😀 The weight would be about the same, but ABS is harder to print, in addition to that, ABS is soft and the gears would wear out a lot faster. I guess a benafit of ABS is that it can maintain higher Temps, but if you keep things cool PLA works better,its easier to print and its cheaper.
Some instruction can be found in the 'print orientation' document linked in the description and also on the Thingiverse page there is instruction. Basically, use high Temps between 210 and 220c On drive parts use 0.25mm layer height On chassis use 0.3mm layer height. On chassis 3 perimeters is fine On drive parts (anything that moves) use 6 or more perimeters Set infill to 10% for all parts
Yes sir.... I'm a Mechanical Engineering student there. And yeah I found it under the community page on his RUclips it has you in about the top 15 under subscribers
@@EngineeringNS ty for the reply. I am currently using an anycubic i3 mega. But I am pretty new in the field of 3D printing (few months), all the models I printed were quite basic and standalone, nothing compared to your RC car. But I have the tool and the software, so in the future I will to print more complex structure. Thanks for sharing the video and the info! Stay safe and keep up!
In my personal experience, that is not the case. I've had mechanical parts that have lasted for years. Even the rear differential in Tarmo3 lasted a very long time and to this day hasn't stripped. If it sits in the sun for months or in water maybe that will be an issue, but if you store it inside your house it shouldn't be a problem. Plus, if someting gets weak after a while, just print a new part.
i realize that you're emphasizing the lack of wear with PLA, but i want to make this and give it to a friend as a gift. i could send him spares, but he would never repair the car. it's not in his skillset, and he won't want to take the time. in that case, which filament would be best?
Sorry for slow reply. I would not recommend this project as a gift. Let me see if I can explain why: Even off the shelf non printed cars break parts constantly. The parts on those cars are inarguably stronger than 3D printed parts. It's just the nature of high performance RC cars that parts will break. So I don't think you will get away from that by using a different matirial. In addition to that, I wouldn't recommend this project to anyone who is not mechanically inclined. It's very mechanically complex and would be overwhelming If you dumped it on someone who just wants to drive an RC car. This project is geared towards mechanically inclined makers who would rather build their own stuff than buy something expensive from the store. It's also for people who enjoy mechanical complexity--Thats why I live it despite the fact that believe it or not I'm not really interested in RC cars as a whole.
That being said, I don't know what matirial is best since I've never used anything other than PLA--However I believe that PLA's hardness makes it one of the better options. Maybe nylon would be better? I don't know.
Hello nice project, have you finished your vacuum cleaner that is on thingiverse ? because i want to build a similar project but with new features, if you have problems i can help you.
I haven't finished it. Its been on the back burner until recently. Though I have learned so much from other projects I am thinking about restarting the vacuum project because I think I can make it much better. Just low on time.
Not on this car, but on an older one I had printed inner diff gears, the problem is that they stripped often. It works, but when they strip you gotta take everything apart to replace them.
@@EngineeringNS right I see. That's when I wonder if using poly carb or carbon reinforced filaments become a worthwhile endeavor. Thing with printing diff bits is theyre so small you can likely get way with printing it without warp even in a non heated enclosure if the heatbed can get high enough.. then again the cost of a spool of the stuff is more than the cost of a metal diff! How is V4 coming along? Any chance you could just have a ramble at the camera regarding it? Just an idea otherwise I'll just patiently wait for the release :-)
On V4 I plan to make the diff bigger to handle more power. In that case printing those gears may be more viable. Or as you mentioned, printing with a stronger matirial could work. It's worth a try if you have some matirial already. If you do decide to go that route, let me know I can send you part files so you can modify them. Haven't gotten far on V4 yet, school is taking a lot of my time--done a lot of planning for the design, but havent implemented most of it. I bought some things like the motor. I'll post updates to Instagram before too long.
You are a stud! So cool that you do all this work and thought into a project that dipshits like me can print and get into RC cars without selling my kids into slavery. (Now their just for rent). No, really Thanks man !! This is Awesome!
hi sir, nice project. iam printing your design, but iam having problem sourcing this (Traxxas 5382X Differential Gear Set) any suggestion sir, please help.. thank you
@@marlonglodo1930 Try doing a google search for it. --here is an ebay result. www.ebay.com/p/Traxxas-TRA-Differential-Gear-Set-5382X-Tra5382x/691217591
Well it would have less torque to my understanding. Also higher motor RPM means more heat in the gearbox so greater chance of melting gears. Of course this may not be much of an issue but I can only say that the car is reliable if you build it in the same way as I did.
@@bryanharmon4564 I believe you can do that though Thingiverse there is a 'tip the designer' option--But don't sweat it man, I'm much more excited to see what modifications people make to the design!

Use the Traxxas gearset in the BOM. The open diff is shown in the video toward the end. You can see how it goes together.
genuinely surprised the gears hold up to the abuse so well, even if the motor is on the smaller side, at least for a 1:10

Thank you! Let me know if you decide to print it, I want to see!!
That's amazing!
Links are in the description for all the files and parts needed.
There are video to the assembly?
Building mine right now
Post pics, I wanna see it! I'll follow you on insta
what transmitter and receiver did you use
I used a super cheap combo from Amazon. Don't recommend it. It's garbage I want to get a new one soon. Any 3 channel rc car reciever should work.
Could you make a mini skateboard like this?
I mean I'm sure you could, there would be some large engineering challenges associated with the massive load of a human though.
i realize that you're emphasizing the lack of wear with PLA, but i want to make this and give it to a friend as a gift. i could send him spares, but he would never repair the car. it's not in his skillset, and he won't want to take the time.
in that case, which filament would be best?
Sorry for slow reply.
I would not recommend this project as a gift.
Let me see if I can explain why:
Even off the shelf non printed cars break parts constantly. The parts on those cars are inarguably stronger than 3D printed parts. It's just the nature of high performance RC cars that parts will break. So I don't think you will get away from that by using a different matirial. In addition to that, I wouldn't recommend this project to anyone who is not mechanically inclined. It's very mechanically complex and would be overwhelming If you dumped it on someone who just wants to drive an RC car.
This project is geared towards mechanically inclined makers who would rather build their own stuff than buy something expensive from the store. It's also for people who enjoy mechanical complexity--Thats why I live it despite the fact that believe it or not I'm not really interested in RC cars as a whole.
That being said, I don't know what matirial is best since I've never used anything other than PLA--However I believe that PLA's hardness makes it one of the better options. Maybe nylon would be better? I don't know.
Hello nice project, have you finished your vacuum cleaner that is on thingiverse ? because i want to build a similar project but with new features, if you have problems i can help you.
I haven't finished it. Its been on the back burner until recently. Though I have learned so much from other projects I am thinking about restarting the vacuum project because I think I can make it much better.
Just low on time.
@@EngineeringNS Okay, lets me know when you restart this project I will gladly help you.
damn fine. gotta print one now!
So clarification on the differential, recommended on the rear, none on the front? How about a printed diff?
Front diff recommended. Rear can be printed locked diff.
@@EngineeringNS has a printed diff been attempted? I could be quite keen to try.
Not on this car, but on an older one I had printed inner diff gears, the problem is that they stripped often. It works, but when they strip you gotta take everything apart to replace them.
@@EngineeringNS right I see. That's when I wonder if using poly carb or carbon reinforced filaments become a worthwhile endeavor. Thing with printing diff bits is theyre so small you can likely get way with printing it without warp even in a non heated enclosure if the heatbed can get high enough.. then again the cost of a spool of the stuff is more than the cost of a metal diff! How is V4 coming along? Any chance you could just have a ramble at the camera regarding it? Just an idea otherwise I'll just patiently wait for the release :-)
On V4 I plan to make the diff bigger to handle more power. In that case printing those gears may be more viable.
Or as you mentioned, printing with a stronger matirial could work. It's worth a try if you have some matirial already. If you do decide to go that route, let me know I can send you part files so you can modify them.
Haven't gotten far on V4 yet, school is taking a lot of my time--done a lot of planning for the design, but havent implemented most of it. I bought some things like the motor. I'll post updates to Instagram before too long.
What is the top speed you have achieved w this model ?
I don't know the exact numbers but I'd guess around 30mph. I don't have any way to measure it at this point.
You are a stud! So cool that you do all this work and thought into a project that dipshits like me can print and get into RC cars without selling my kids into slavery. (Now their just for rent). No, really Thanks man !! This is Awesome!
hi sir, nice project. iam printing your design, but iam having problem sourcing this (Traxxas 5382X Differential Gear Set) any suggestion sir, please help.. thank you
Did you try the link in the BOM document?
@@EngineeringNS yes sir i try it. But the traxxas 5382x diff gear set is not available here in my country. Amazon doesnt ship here in philippines
@@marlonglodo1930 Try doing a google search for it. --here is an ebay result. www.ebay.com/p/Traxxas-TRA-Differential-Gear-Set-5382X-Tra5382x/691217591
How much kv motor do you use?
1180kv probably anything less than 1300kv will be best
@@EngineeringNS why less than 1300kv? mine seems to be running okay with a 3000kv of the same dimension so far
Well it would have less torque to my understanding. Also higher motor RPM means more heat in the gearbox so greater chance of melting gears. Of course this may not be much of an issue but I can only say that the car is reliable if you build it in the same way as I did.
Are you going to release the .stp file so we can play with it in Fusion 360. Let me know, I will tip for the file. Thanks
I'm concidering it. Stay tuned. I'll post about it on Instagram if I do.
@@EngineeringNS I think it will help you also get more exposure. Thanks I hope you do.
@Bryan Harmon You are right. I wanna see what you come up with! bit.ly/tarmo3files
@@EngineeringNS Very Cool of you. How can I send a tip?
@@bryanharmon4564 I believe you can do that though Thingiverse there is a 'tip the designer' option--But don't sweat it man, I'm much more excited to see what modifications people make to the design!
Какой масштаб модели полулся?
