Dremel Bit

thingiverse

So, I lost my dremel sanding bits and I wasn't in the mood to go buy some more... so.. I knew the M3 screws fit the dremel... so all i had to do, was 3d print a sanding bit, with a hole for the screw and superglue a scrap piece of sandpaper and done! You have a cheap new sanding bit! =D You can take the idea and modify it to have bigger, smaller diameters or even a plate disc! =D EDIT: Added de Flat version. Its intended for a flat disc sander. 5mm diameter, i use it that small because i dont want to force the dremel going with a bigger diameter. But you can glue a bigger Foam disc and should be good to go. (in the picture, i used a 5mm black eva foam that i glued to the piece with barge cement, and then added a sand paper using the same method.) (the bit with a worn out sandpaper is V1, the other one is the brand new v3, which has a smaller hole diameter so the screw doesnt wiggle, and a bigger hole for the screw head Print Settings Printer Brand: Prusa Printer: Prusa Clone Rafts: No Supports: No Resolution: 0.15 Infill: 20% (fasthonycomb in S3D) Notes: It has a tight fit, so you just put the M3 screw and then screw it through the hole. You need: 1-M3 screw (the lenght you wish, i use 22mm ones. wouldnt recomment anything shorter than that) 2- Sanding paper, the grit you wish. 3- Super glue. Instructions: 1-Screw the screw through the hole. 2-superglue sand paper. 3-sand untilg fatigue attacks.
