low cost filament rack

When spools are stacked randomly, left on the floor, or shoved into boxes, they can get damaged, tangled, or forgotten about.

The design focuses on being as simple and low-cost as possible. I avoided unnecessary features and extra material, using only what’s needed to hold standard filament spools securely. This keeps the rack affordable, easy to build, and effici
