FillaRoller Single Part

Remixed to be a single part. I mainly used the original for inspiration and for the Ender lock nut dimensions.

This is a single part roller, you just need 2x 608 bearings (22mm outer diameter, 8mm inner diameter, 7mm thick). The bearings just slide onto the posts. The filament roll turns on the bearing outer race, so it's very low friction and noise (the stock Ender roll holder squeeked on my machine). It's sized to suit the Overture filament rolls I'm using, which are about 68mm wide. The Rhino file is included if you want to extend the model to suit a different roll.
