Human: Boost print quality on your Ender 3 with this super-efficient filament holder. Universal spool holder that lets your spool spin freely, using just 4 standard skateboard bearings. Position it anywhere on a tabletop or desk near your printer for optimal results. Works best with side-loading printers like the Ender 3. Suitable for any width filaments - simply position the sliders under the edges of your spool. Instructions: Print 4 copies of Filament_Spool_Holder.stl and snap them together around the bearings. To ensure a secure fit, print 4 additional copies of FilamentHolderPin.stl to insert into the top holes. Bearings: Note: You'll need 4 separate bearings that aren't printed. I recommend using standard skateboard bearings with dimensions: 8mm x 22mm x 7mm.
