Neptune 4 Plus/Max Filament Sensor Mount with Bearing

This is my take on a filament sensor for the N4+ and Max. Similiar to the author's original make, it uses a 608 bearing to provide smooth rotations of the filament sensor.

NOTE: Design for the use of an alternative spool holder/roller as this will use the original T-nuts initially dedicated to the stock spool holder.

Instructions:
1. Insert the 608 bearing to the slot and slide it down into its seat.

2. Insert the screw fitting and screw on the sensor, install the PTFE  tube holder.

3. Mount onto the T-nuts on the printer.

Modified to use on Neptune 4 Plus/Max. Lowers the sensor position for the convenience of enclosures.
