Very simple filament reel holder

This is a remake of airtrippers pocket reel holder designed to use a single 625 bearing for each roller. It's as simple as I could get it and still work. The Idler pulley is from lincomatic and is unchanged.

Seems I spend more time making parts for the printer than I do making other stuff. Hopefully some day this thing will just work and I can get to creating useful stuff.
