About this 3D model

With this bearing-based filament holder, your externally mounted filament can roll resistance-free. I print a lot of TPU and having the filament be fed unresisted is pretty important. This is a heavily remixed and redesigned version of Eldenroot's Spool holder . How to assemble Print all parts Glue the screw into the Roller Tray (it's a tight fit on purpose) Screw the roller tray onto the external filament arm (Left or right) Assemble the rollers with the bearings and drop the assembly into the tray Non-Printed parts 2x ball bearing - type 608zz or similar (608 series) Some CA glue and highly recommended accelerator , to glue the screw into the roller tray. What is different in this model? Requires no hardware ( does require CA glue) Much lighter, less parts. It can be mounted left or right (the old model seemed to only work on the right). Most important: This places the roller close to the centerline of the external holed which keeps the filament spool from pulling itself on top of the inner bearing, Updates: 10/07/2024: Added print profile “V3” that includes the standard roller, and the rimmed roller 07/17/2024: Added single roller with a rim at each end to prevent the spool from ending up in the bearings. 07/12/2024: Added a new profile with a single roller Added an adapter to mount the roller to this AMS riser for an X1 Carbon or P1P
