Low friction spool holder

thingiverse

I picked up some small filament spools that didn't fit any of my existing spool holders, so I came up with this low-friction holder to sit behind my printer. Two skateboard bearings are needed for the roller on this setup. It's a bit of a tight squeeze to get them in place at first (brute force and ignorance worked just fine for that). The bearings I used can be purchased from Amazon through this link: http://amzn.eu/9vQ52eK
