This is a simple wall mounted filament spool holder that will accept any size dowel up to 2". I used some 1" wooden dowel rod I had lying around.
You can use the included screw holes or command strips depending on how much weight you will hang on it. I recommend using screws. Try to find studs if you plan on putting a lot of weight on it.
I printed this using PLA with 5 walls and no top or bottom layers to show off the infill, and it is plenty strong. I can hold 10 spools with no worries at all.
