I created this remix to make the Filament Holder usable with regular Wardrobe/Clothes Rods (15x30mm oval rods).
Smaller rods, taller rods or even perfectly circular rods will also fit, as long as they are 15mm wide.

Remember to mirror the model and print one of each. I've added a .3mf file which includes the model in both the original orientation and mirrored, plus 6 pins to mount it in the closet.
