Add storage while reusing empty filament boxes with a scalable, wall-mounted solution.

For peace of mind, I mounted the top holders with screws and then used command strips every other which has held up well so far.

Each bracket includes screw holes and recessed spaces for command strips.

The small triangular pegs lock each bracket together.

For bigger print beds 250mm and up:

• Print one top shelf and however many bottom shelves you want
• Two triangle pegs per shelf that you'd like to connect

For smaller print beds:

• Print a top left and top right
• Print a bottom left and bottom right
• 2 circle pegs for each shelf to connect the two sides
• 2 triangle pegs for each shelf you'd like to connect
