Simple spool holder for 3DPN's 1x2" shelf, optional bearings and screws

Keeping it simple, a basic arm for mounting a standard roll of filament on a shelf made out of 1x2" wood.

The design can be used as printed, or you can add two standard 608 (skateboard) bearings which sit on the printable bearing rods and allow for a smoother rotation of the spool.

This is designed to be easily printable on all printers, and easily moved to different locations on the shelf, although can be fixed in place using the two screw holes on the rear.

#highfive

Update: Added a slightly shorter version of the bearing rod because the original was a bit tight. I also reduced the size of the end piece as I noticed it was a bit tight on some of my spools. The updated version is shelf-spool-holder-v2-smaller.stl
