Supplied in each kit are 4 black thumb screws, designed to be leveling feet for the printer. Additionally, there are 4 clear rubber bumpers to go on these. Don't use these clear bumpers just yet! The way it is, the bumpers will fall off of the thumb screws within a week. I am working on designing a plastic end cap to go over the bottom of the extrusions which you can then stick the rubber feet to. They are squishy enough that they will compensate for any height variation in the legs!
So for now, just use the thumb screws without the rubber feet on them (you may need to unscrew all of them a bit to get the proper height to clear the control board)! I'll work on the plastic feet so once you guys get printing you can print out these new feet and add the rubber bumpers on those!
Attached are the new feet files for the printer which you guys should print and use when possible. I can't exactly test them on mine since I have different sized extrusions, but let me know if anything collides or if they are too tall/short, etc. I'd recommend testing them out before adding the rubber feet to them just to make sure they will work alright, as the feet will be difficult to remove once installed! I wouldn't recommend gluing them on since you will need to remove these if you ever want to remove the bottom plate. I can add a version with a bolt in it as well but since the rubber foot would have to cover the bolt head I'm not sure how that would be either!
Hey everyone, I just thought I'd show mine. I printed them at 0.2mm resolution with a brim to help them stick to my current printer (since my board hasn't arrived yet...) and it all turned out nicely. I would recommend when you're affixing them you loosen your L brackets first so they can seat in their respective holes on the print nicely, and then tighten them while you push down on the part (printer upside down). That will make the L brackets pinch the printed part slightly, as well as ensure that the acrylic panels are tightly held in. Obviously don't push too hard to avoid damage, but for me it worked just fine. Just make sure your particular printer has proper tolerances to accommodate the pieces. let me know if you all have any other ideas, or wish for me to elaborate on anything.
Also, with my Prusa I3 style printer (heavily modded), all of the tolerances were perfect without any adjustments. All the pieces fit well, and the bumpers fit perfect. Well done Andrew! Another spot on part.

Great glad to hear they fit well! I had to do a bit of guesswork since I didn't know exactly how far out the l brackets stick out on the beta version but I'm happy to see that they fit nicely! If you or anyone else has any advice for improvement let me know! (that goes for all the parts, printed especially, as a matter of fact!)
