Coffee-mill Adapter ver. 2

Previously, I developed a coffe mill adapter like many other makers (https://www.thingiverse.com/thing:3874672). However, I realized that the 3D printed shaft can be broken easily even I used 100% infill. So, I changed the strategy and decided to use the driver pit as a shaft.

This attachement is designed to use PH2 plus or PH6 minus driver pit.
This version is still a developping version, and may not suIte to your drill pit.

I set outer layer number 4 to acquire sufficient strength.

Material: PLA
Infill: 100%
Support: NO
