This spool storage rack is a simple modular setup that lets you extend it as far as you need by linking the pieces together. I currently made two lengths, 72mm and 216mm, so you can mix and match depending on your space.
Whether you place it on your desk or inside a cabinet, it stays steady, and the spool won’t slide around easily. If you want a cleaner workspace or just want your filament to behave, this holder does the job nicely.
