Simple filament hook that can be stuck to the wall with a large command strip.

The small one has a 2.5" clearance which fits most 1kg spools I tried. The longer one has 73.8mm of clearance for spools that are a little wider. The length can be changed easily with the freeCad file (in the .zip). You just need to change the length of the "pad001".

large command strips claim to hold up to 5lbs of weight so they should hold the hooks + a full 1kg spool of filament. I have not had any issues with them falling down yet.

I made this because I needed a renter friendly storage system for my filament, and I really liked how it turned out so decided to share here.
