Rack for filament spools

thingiverse

I built a filament spool holder using brackets. I used three of them for a one-meter-wide shelf. Two round wooden broomsticks served as carriers. You can use anything with a 25 mm diameter or less. I also added 2.5 mm thick steel wires, gluing them into the small hole to make the plastic bracket more stable. The wall mounting holes have an 85 mm central-to-center distance. After cutting out the two supporting ribs that separate the round hole from the slot, you can screw a regular three or three and a half millimeter screw into the wall. Slide the bracket over the screw heads and pull them down slightly to get the screws into the slots.
