Filament Spool Holder

Fits 1Kg spools 54mm hub size and larger. Mounts on top 20mm x 20mm rail of printer to keep spool up off of desk. Uses 2 608 bearings creating a smooth rolling system.Look at pictures and email me if you need more information. It's a simple design, 2 printed parts and 2 bearings. Pieces are printed vertical to minimize cleanup. There are 2 styles of saddle, one that runs near the top of the printer and one that brings the spool up another few inches to clear taller parts. I don't print excessively tall prints so the short one works well for me. You decide.
