Introducing a simple yet effective spool holder that offers a sleek and practical solution for your filament management needs.

This 3D model comprises two parts that are easy to print and assemble. It is designed to fit perfectly onto a horizontal 2020 extrusion, ensuring stable spool placement and smooth filament feeding.

Its versatile design accommodates different spool sizes, while its split design enables efficient printing.

This spool holder operates with exceptional smoothness and does not require bearings or PTFE tubes.
Additionally, although the surface can be sanded, the contact area is so small that this step is largely unnecessary.

Moreover, this spool holder works great with cardboard spools as well.

PLA is just fine for this.
