Low Friction Spool Roller Arm

I needed to print some 85A TPU and therefore needed a spool roller that had the lowest friction possible. When I found this roller I just needed to make an arm that mounted to the printer itself. The arm is long enough to fit 3kg spools, as I use those from time to time, but I have also included the Fusion 360 and step files if you need to resize/modify it.

For me, with the combo of the bearings and the straight filament path, it worked like a charm and eliminated all issues with the TPU loading into the printer.
