Snapmaker Filament Sensor (makerbot endstop)

This is a holder for a makerbot endstop switch and is supposed to reside on the 3d printing module. The top of the holder houses a makerbot endstop switch which can be hooked up to a raspberry pi running octoprint (via GPIO Pins).

THe distance between the endstop to the top of the 3d printing module is about 40mm, which should be enough time for the pause command to be sent before the filament goes in.

Also, the attachment is not bolted secured down to make it easier to change filament.
