Spool roller with filament sensor

thingiverse

This is a universal roller designed for the Creality CR10 but can be easily adapted to fit any printer with a standard 2020 profile. To build this roller, you'll need the following materials: - Four 5x11x5 bearings - Four M5x25 screws (the length of these screws isn't crucial, but they should be long enough to securely hold the rollers) - Four M5 Hex Nuts - Two M4x10 screws - Two T-nuts to secure them on the 2020 profile There's a washer incorporated into the printed parts, which serves to space the rollers from the roller holder. However, due to machine tolerance variations, you may need to adjust the height of these washers before printing them.
