模型说明
I made this for my proxxon rotary tool. It's ipired by https:www.thingivee.com/thing:1024834, but I've redrawn it from scratch.
Resulting drill bit tip angle is 118°. You also need to undetand what relief angle mea.
I've printed mine from PLA with 15% honeycomb infill. Works well.
This thing was made with Tinkercad. Edit it online https:www.tinkercad.com/things/lIblABgnLZp
