Summary

Designed this rather slim yet sturdy spool holder to fit 2kg rolls of filament. To put it together you will also need:

• 2x 6005 2RS roller bearings, (ID 25 mm, OD 47 mm, Depth 12 mm)
• 4x M4 threaded inserts, depth 5mm
• 4x M4 bolts, depth 5mm

Prints without supports, you need two frames and two joining pieces and one axle to print a complete assembly.

Edit: Added a filament holder (clip on and wall mountable) to keep unused filament nice and tidy.
