This handy dust collector was sent in by Dave. The suction holds the vacuum to the wall so you can drill dust free!
This is a partial redesign of our original DC, https://www.thingiverse.com/thing:3207227.
Things are roundier, and at least on our first tests, suckier, likely due to the rounder passageways and slightly cleaner interior. We also wanted it to stick to the wall on its own, which this does, with no post-processing required: https://youtu.be/g8TKLEhH0KE
Two files are available; dust disk horizontal, and vacuum port horizontal (e.g., flipped vertially). We’re still printing with the dust disk horizontal with no supports, which means the inside gets a little stringy. In vertical most it might print pretty well without supports, but Simplify3D puts a lot of supports up during print prep
