Sherpa Mini Filament Sensor

I wanted a filament sensor for my Sherpa Mini, but I did not want to print a new body, so I designed this one.

Back is optional I made 2, one to use a 3pin JST-XH connector, the other just a hole to pass through the wires.

BOM:

1 - 4mm ball bearing 

1 - D2F switch without lever

1 - PTFE Collet

1 - 15mm PTFE to put between the sensor and the Sherpa

2 - M2 8mm self tapping screws if you want the back. (I just cut some 12mm I had)

Changes:

Made the attachment points thicker.
