My polishing machine broke down so I made this polishing tool bit for a standard drill or dremel. I used this to polish my car's windows and it worked very well. Use some double sided tape or glue to stick a piece of microfober cloth to the bit and you're good to go. Printing time is 20 to 30 minutes and you should print this with a solid infill (otherwise it will crack while tightening your drill).
I printed this in PLA at max speed
