Spool Roller

Compact Filament Roller System

I designed these a while ago and have been using earlier versions for a long time with great results. They are smooth, compact, reliable, and use minimal parts.

The system has worked beautifully with TPU inside an enclosure, providing very smooth and quiet operation. Roller 2 was designed to replace some of my older spool kits, making loading and unloading much easier thanks to the pivoting mechanism.

• Reliable operation with TPU and enclosed printers

Notes

At the moment there is no retraction/tension system included, although one could easily be added since there is extra space around the roller and bearings.

Let me know how it works out for you!
