Bondtech Prusa i3 MK3s Sensor Add-On modded for bowden (PC4-M6 and PC4-M10)

Update 2019-03-03: I've added a Version 2 of the cover. The Lever-screw now is used to secure the cover as well. You'll need an M3x12 screw now...

Just a quick remix of the Bondtech Prusa i3 MK3s Sensor Add-On. This is intended to give a home to a PC4-M10 connector and connected (actually pushed through) PTFE-tube. As such I've added an M10x0.9 thread (cause that is what my connectors use) on the sensor cover and modified the filament entry point of the housing to receive a PTFE-tube.

There is also a version for PC4-M6, here only the sensor cover is different, the rest of the parts is unchanged.

This is untested, but the threads usually work just fine.

One word of caution: the original design has the lid just snap into place (https://github.com/BondtechAB/Bondtech_Prusa_i3/blob/master/Doc/Sensor%20Add-On%20V1.0.pdf) - no idea how the additional forces of an attached tube will come into play. OTOH, the inner filament should help against it...

The Fusion 360 files are included.
