Spool Holder for 2020 Aluminum Extrusion

Minimalist spool holder to mount on 2020 extrusion. Designed for simple printing and need only 2 additional 608 bearings.

Since this is a rather loaded part, I would recommend printing with 5 perimeters and not too small layer height. Main body has a extra thin walls to simplify printing without generated supports (only a few 8-10 mm bridges will be printed).
