Simple shelf brackets, intended to hold a wooden dowel, for supporting filament printing spools. I'm using a 3/4" dowel rod. Does a decent job of getting this stack of filament spools out of my way. Use or modify as you will.

Slightly modified to more easily print... Rounder edges, better fits 3/4" dowel, slightly widened base for better adhesion.

I've printed these in PLA, with 20% infill. Stout enough for my purposes. Thinking I might run off a set in PETG, but I'd want to print 'em one at a time, with how bad PETG strings.

Upscale by 20% if you want to use a 1" dowel.
