The manufacturer sent a whole new robot vacuum as a replacement, but when I asked what to do with the old broken one they said I can keep it 😆
Thr old ones bottom roller brush thing stopped spinning. The plastic is completely gone. In the photos, you can see a nice sharp square for the roller brush in the new one, which is completely gone in the old one. I think it had bad tolerances or something.
@mhamzahkhan 3d print+acetone/MEK welding?
@mhamzahkhan In that case, I recommend FreeCAD, Shaper3d if you have an ipad, Sketchup, or Fusion360. There are loads of tutorials on the last 3, but they all cost some money. FreeCAD is completely FLOSS, but it's a bit of a doozy to learn and pilot.
Edit: Oh, and if you do MEK/solvent welding, you NEED a respirator with an organic vapor cartridge!!!
