A universal spool holder I made to mount in different ways. This is not meant to work while printing but more for storage.

This contains screw holes if you want to screw it down, areas to zip-tie it (my method for the wire shelves I have), and enough room on the bottom to put rubber feet.

I cut as much off of it as I could to cut down on filament. 2 average size spools fit on one holder. I added pegs you can glue on the side to match additional holders up as well as a locking pin for the center.

Inner fill: 15%

Brim: No Brim

Filament: Whatever you want. My photos are in PETG.

Supports: No supports
