Free Moving Filament Sensor Mount

thingiverse

This Free Moving Filament Sensor mount will allow the sensor to rotate with the extruder, reducing the tension on the filament and lessening the grinding and noise the filament makes on the sensor while printing to the extremes of your print surface. I based the the bearing mount portion off <a href="https://www.thingiverse.com/timbolton/designs">TimBolton's</a> <a href="https://www.thingiverse.com/thing:2161940">Micro Single Spinner Fidget </a> . It was compact and does the job well. I'm using 5 M3 screws to hold the mount together and 2 M4 screws to mount the the mount to the top of my Ender 3. The 2 M4 screws screw into <a href="https://www.amazon.com/gp/product/B01GCDG2RI/">Tee Sliding Nut</a>. I'm using a cheap <a href="https://www.amazon.com/gp/product/B08QJDSZCL/">BIQU Filament Break Detection Sensor</a> as my filament sensor. I'm using <a href="https://www.amazon.com/Bones-Reds-Skateboard-Bearings-pack/dp/B000FDRQ1S"/>Bones Reds Skateboard 608 Bearings</a> and my center bearing.
