Smart Filament Sensor z-cap for RatRig V-minion (left-mounted)

Remixed the stock RatRig V-minion z-axis cap to add a bracket mount for the BTT Smart Filament Sensor.

This is the left-mounted version of my previous remix. 

I'm using it in combination of Michael Whitley's back cover for the sensor.
For space reasons I couldn't use his mount as it sticks to the left, but it's a good design and you should check it out.

There's a version that uses a long M3x20 screw + nut to fix the sensor, and another that uses M3 heatset inserts.

Cable management using zip ties along the back of the hook.
