Filament and Wire Spool Rack

thingiverse

Wall-mounted rack for storing filament or wire spools, capable of holding any spool up to 240mm (~9.4 in) diameter. A metal bar or wood dowel can serve as a crossbar; a 10mm diameter bar fits well, but various sizes will work effectively. Typical wall screws used are 6 x 1-1/8 inch drywall screws. The screw holes may require additional support while printing. I printed this in ABS and it is surprisingly sturdy. A high infill percentage is recommended (80-100%).
