Shelf bracket for filament spools.

I used 22mm wooden rods to make the shelf. Mounted to the wall with 4mm screws (the bottom hole is a bit bigger so you can also use 5mm screws).

There are 2 versions of the design. I recommend printing the 20mm wide version for maximum strength and the additional 15mm wide ones only if you need a longer shelf (mine is 120cm long and holds up great with just two 20mm wide brackets).

I printed them in basic PLA with 5 perimeters and 0.3mm layer height.

Quick thanks to Mechmaster as this design is heavily inspired by his brackets.
