Wall Mount spool holder

Inspired by the roller style spool holders, this is a wall mounted version.

You'll need
(2) 8mm or 5/16 bolts, at least 4" in length.
(4) matching flat washers
(2) matching nuts
(4) 608 bearings

I printed at 35% infill, seem plenty strong. And I also only used the top mounting hole (one on each) and seems to be holding fine after a few hours of printing.

Have included the STEP file for anyone that wants to mod it.
