Drill bit sharpener for 20mm PROXXON tool

I made this for my proxxon rotary tool. It's inspired by https://www.thingiverse.com/thing:1024834, but I've redrawn it from scratch. Resulting drill bit tip angle is 118°. You also need to understand what relief angle means. I've printed mine from PLA with 15% honeycomb infill. Works well. This thing was made with Tinkercad.
