3D Printer Filament Spool Roller

I needed a slick way to set up the filament spool outside the printer. Quickly created this nice bearing design. The filament just rolls of the rolls as smooth as a 80s love balad.

Except for the plastic you need

- Two 7mm thick skate board bearings. 8mm hole in the middle.
- Two M8x30 bolts
- Four washers
- Two M8 Nuts, i've choosen to go with the old round headed so i don't see the thread.

I hope i don't need to mention that you need to build two of these per roll... :P

Happy
