Slim Spool Holder

It was just a fast throw together, but has been working well for me, so I thought I'd post it.
Only problem, I used parts laying around to help me build this. That being said, the ball bearings may not be a common size that would be around a 3d Printer's house.

Also only intended for 200mm by 65mm filament spools. Other versions will probably come to account for smaller 500gram spools.
