Update: v1.4 added nubs to hold USB in place better and tighter tolerances on clippers.

I printed another user's tool holder, but was not satisfied with the tolerance and layout of theirs so I decided to design my own. Included is the SOLIDWORKS file I used.

The type of support I used is the 'normal support structure' on Cura

Settings:
Infill density: 20%
Print speed: 60 mm/s
Supports: ON (The support is needed for the part that slides into the aluminum)
