Multi-Spool Filament Stand

This project started with a small moment of inspiration—
a leftover piece of PTFE tube that was about to be thrown away.

Then it hit me:
“PTFE is extremely low-friction… could this work as a bearing?”

From that idea, I began designing a simple filament holder that works with both 250g mini spools and standard 1kg spools—no adjustments, no extra parts.

PTFE tubing has very low resistance, which makes it surprisingly effective when a filament spool is used vertically.
By using a short piece of PTFE tube as the common contact point for both small and large spools, I was able to create a holder with:

Fewer parts

A clean, minimal structure

Smooth and stable spool rotation

No ball bearings required

The result is a simple, practical, and elegant filament holder, inspired by the idea of making the most out of ordinary materials.

No unnecessary complexity—just a smart use of physics and materials.
Sometimes, the best upgrades to your 3D printing setup come from the simplest ideas.
