I designed this filament spool roller to go on top of the Prusa IKEA enclosure. I use it for the filaments which i do not have stored in the dryboxes (for example PLA). The roller is designed for 1kg filament spools (dimensions approx. ⌀200mm x 70mm).

Parts required for printing:

1. filament_roller_botom (1 pieces)
2. filament_roller_wing or filament_roller_wing_patter (2 pieces)
3. filament_roller (2 pieces)

Assembly:

1. Insert two 608 bearings on each fillament roller wing
2. Insert both filament rollers on bearings
3. Join both wings togeter
4. Place the wing assembly into the botttom part

Tip: for a sturdy construction use glue to assemble wings into the bottom part
