Drill bit sharpener for 20mm PROXXON tool
thingiverse
I created this accessory for my Proxxon rotary tool, drawing inspiration from the design found at Thingiverse, but rebuilding it entirely from scratch. The resulting drill bit tip angle is 118 degrees. It's essential to grasp the concept of relief angle as well. My prototype was printed using PLA with a honeycomb infill of 15%. The results are quite satisfactory. This project was developed using Tinkercad. You can edit and modify it online at tinkercad.com/things/lIblABgnLZp.
