Modular Spool Storage Rack

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. Added on 2025.11.27: Desk Spool Storage Rack.It features side walls to keep the spool from sliding, and the bottom includes slots for anti-slip pads to improve stability on your desk.Available in 1-spool, 2-spool, and 3-spool versions, so you can choose whichever fits your setup.
