3D Printer Filament Roller

This is a 3D printer filament spool roller I designed. It's perfect if you want to prevent stock spool holders from creating unnecessary friction or if you want to relocate the spool away from the printer. It also fits perfectly in a Rubbermaid 21 cup container should you want to use it in a dry box application for hygroscopic filaments.

For the files there are 2 variants. Download Filament_Roller_SideHEX_NUT_VERSION.stl if you would like to use hex nuts.
Download Filament_Roller_SideHEATSERT_VERSION.stl if you would like to use heat inserts.
