Hey, don't know if you will see this but I specialize in HVAC and have a suggestion for this style of ventilation.
Ideally you want another hole made on the box to ensure air circulation.
The way fans work especially when ventilation is concerned is off of pressure differentials.
You create a negative pressure space before the fan and a positive pressure after the fan. However because the box is mostly sealed the negative pressure box cant take in new air.
In turn this creates strain on the fan motor/ causes it to operate at a reduced speed. Thus reducing the amount of air it's moving.
When you add a second hole to the shell it allows new air to be forced into the shell which allows more air to flow out.
If you worry about fumes potentially escaping this hole. You don't need to be new air is always going to be sucked into this hole and the bad air is always going to be sucked out. When you are not running the fan you just seal both holes.
I have an elagoo saturn 3 and it comes with a ventilation hole already towards the bottom. I use that as my fresh air intake. I then made a new hole directly on top of the box with some flex duct hooked up to that into my exhaust.
Thanks for your time if you got a chance to read this.
I’ve been googling for hours looking for this info thank you for this
Also, does all that airflow with the two hole system affect the quality of the prints? Temp change etc?
@@gehrkea it shouldnt effect the print quality. The temperature within the enclosure is going to be almost the same temperature as the ambient air outside the enclosure. So it shouldn't change anything.
With the ventilation being taken from the box the ambient air is being sucked in no matter what. The only difference is how much air is actually getting moved.
With the tight enclosure the air will still be finding its way through the cracks. At least this way you are allowing the air to freely enter which helps increase the total volume of air moved and helps the motor.
The you could change this set up if you wanted. You could have 2 vents so it's sucking in fresh air and then discharging that air. This would eliminate using the rooms air all together. you would be subjecting the enclose to the outdoor air temperature plus any bugs or anything get caught in the air stream. So if you do that method it could effect the quality however there are still ways to mitigate that.
@@andrewh9284thank you so much for replying! I think I finally have the right set up in mind now with all this info.
Mitigating the temperature of fresh air coming from outside would be adding a heater to the printer?
I had a good laugh over the old stylized animation, well done !
Great to see you getting into CAD tools. To fix the bolt offset make it equal to(360/#magnets)/2. Now it should always be correct
Would love to see a tutorial made by you for fusion 360
You know what would be awesome? If you'd also include outlet adapter for EU windows ventillation systems (most of our windows have something like 16cm x 1cm rectangular hole for ventillation). I'd pay for that, mate :D
That kind of thing sounds like a fantastic starter project to learn Fusion 360. Seriously, I'm not kidding. You could get it done in an afternoon with no experience at all, and now you have a new skill that makes your printers even more useful.
Pro tip: the free version of Chat GPT is way better at getting info on how to do stuff in Fusion 360 than google is. The results for "how to on fusion 360" tend to be pretty terrible and are almost always videos when the answer could be a single sentence.
I tried to look that up but I'm not sure I can find what you're talking about sorry! Sounds like a job for someone in the EU with direct access to these vents to model that adapter. Should be a breeze with these new files 🍻
. @OnceinaSixSide Lemme get some fake fusion360 educational license... :D
all windows here open on a hinge 😅 (also EU), they either open like a door, with side hinges, or with hinges on the bottom to vent some air (those only open a bit) - so it's hell to vent things.
@@deebernaers137Have you tried one of those window AC kits from Amazon? They look a bit fiddly but once installed it should be relatively easy to connect these vent files.
This is the sort of future I want to live in. Files that are useful and adaptable. Well done!
Regarding the holes for bolts and magnets, you could have it so the magnet holes form an array between each bolt hole. So you could say 4 or 5 bolt holes or whatever and that determines the symmetry of the array then say 3 magnet holes per sector between each bolt in a B-M-M-M-B style. Since the bolt array is really what you want to get right to match how you want to attach it and then you're just duplicating that short array a number of times to match the specs you want.
This is perfect. I asked about adapting the original design to accommodate for a smaller hose size and this basically allows me to do that so awesome. Now I'm that much closer to 3D printing.
Great Guide! I'll improve mine right now
So I've made some changes to this for use with the Athena printer. It required adding a couple new parameters for bolt spacing and bolt spacing override on the coupler. Bolt spacing maintains the centered between the inner and outer that you accomplished using the midpoint constraint, but if you set bolts to 4 and set a value in bolt_spacing_override it will position the bolt holes on the coupler for a specific square spacing (for Athena's 80mm 4 bolt layout the bolts need to be 71.5mm square, which doesn't work when using the midpoint).
I plan to upload it as a remix to makerworld once it's been validated for athena, but if you're interested I can give you a copy so you can see the formula I used.
This is actually perfect and something i need for my portable AC. Thanks so much man.
This couldn't have come at a better time. I'm building an extraction chamber for a laser cutter and wanting to vent my current resin setup. So I'm printing these as we speak. Thanks!
When you get your A1 Mini, do a 0.2mm nozzle miniatures test. Seems like something you’d enjoy
Also thanks for the subtle nod to my comment haha
Love your work, when it’s in the budget I’ll be sure to hit up your patreon
Nice. Good job, thanks for that.
OMG that's AWESOME!!! The biggest thing to me is having a window port so I don't have to put a dryer vent in the side of the house! FYI, a 45 degree offset will allow you to put a 6-hole and 4-hole pattern on the same bolt pattern diameter
Gotta love MOID. He has such good documentation.
You should do a brief call for action at the beginning of the video, a lot of people aren't going to stay past that outro to see the other one. You can even reference the ending one to keep the opener brief so you don't have to go into the whole spiel about what you get and all the various options.
Maybe I’m just slow, but I can’t find the fusion file for this project. I love your content either way. Thank you for all that you do.
Makerworld is a bit confusing. Follow the link in the video description, then click Download, then click on STL download and it's under there
Wow, I wish I knew how to do this. I have made my own vents and connections but I used Blender. F360/Fusion was too much for me to learn. Well done!
Fantastic with the new parametric version. Thanks!
One small problem; if you change the total diameter to e.g. 135mm, all the magnets in the embedded storage cap are no longer embedded, some are exposed.
I'm trying to fix it, but my Fusion skills are not quite up to the task yet :-)
FYI: Most Slicers supports STEP file importing and for functional parts that's really cool and more accurate than rendering to a poly mesh.
Really not sure why seeing my name scoll by is satisfying...
Jut buy VOC detector and you will see in how much trouble you are, despite the fact that you have ventilation system like that. I had my printer set up with ventilation system and additionally with grow tent. Still VOC's where beyond the scale. To have really safe environment you would need industry grade equipment for ventilation.
i got me a pax closet from ikea... i plan on basically making a grow box out of it... in the top i want a carboin filter with a 420cbm fan leading out of the window... so everything inside the closet wil get sucked in and filtered... i plan on putting my p1s + ams + filament heater and saturn+wash and cure inside. since i also plan on a real grow box with flowers and a airbrush vent in the same room im now looking for a solution where i can hook up 3 fan outs to one big fan outlet... maybe with closeable doors... did u ever made splitters?
How do people do ventilation on cleaning prints? I’ve read it emits way more voc than the printing process itself
Check out the original "Fumes be gone!!" video from 1 year ago; he built an improvised, but functional, hood over his cleaning station that this system can easily attach to 👍
Yep as pointed out there you can easily rig up a flow hood over your work area that this system connects to. You can also attach it to the enclosure of your wash and cure machine and that works great
About how much is the cost in materials? I apologize if this was mentioned in this or the previous video and missed it.
could we free ourselves from the tyranny of magnets with a twist attachment or are 3d printed threads unreliable?
I only have a resin printer, and resin is brittle. Any one have tips on how to print this using resin, and setting up the magnets?
Hmm.. My advice is to just not do that. Before I had an FDM printer of my own I used to just pay people I found through local classifieds to print stuff off for me and it was never very expensive. I recommend going that route - it'll be a lot less time, material, and cost compared to trying to produce these in resin.
@@OnceinaSixSide I actually had a FDM printer before and exchanged it for the resin, haha. Should have kept it and had both!
Any decent solutions for those of us without FDM printers?
Of course! Check your local classifieds for 3D printing services near you. Chances are someone nearby can run these files off for you very cheaply.
@@OnceinaSixSideIt is a little frustrating that an add-on for a resin printer requires a whole other type of printer in order to work - is there a reason this couldn't be printed in resin?
On a separate note, lots of local libraries now have maker spaces and 3d printing resources, and will print files for you just for the cost of the filament! That's my backup plan in case this actually won't work in resin.
@@aclabonte Yeah I get that, and while you can do it in resin, filament is always going to be the better option here in every single way.
Resin really shines at high detail, but falls down when it comes to durability, dimensional accuracy + stability, not to mention waste.
Unless you want to fork out some big bucks for some engineering resin, you're better off just heading down to the local maker space.
At the risk of kicking a dead horse I think it's worth pointing out even if you do buy yourself an expensive resin that ticks the boxes for these parts, you gotta waste a lot of that resin on supports, and if that print fails for any reason the costs will balloon out of control quickly.
God, you're beautiful. Cheers!
Will you make a video that just your rabbit. Call it like "GW wont be able to do this, EVER" than its just a 5 hour long video about your rabbit, but just follow the rabbit
