MMU3 Chimney Modified for PC4-M10 Fitting and Spring Loaded Sensor Adjustment

MMU3 Chimney Modified for PC4-M10 Fitting and Spring Loaded Sensor Adjustment. I used the M10 fittings with my MMU2 because it made it easier for maintenance so I made this for the MMU3. I also loved the idea of Cdbugess's spring loaded sensor modification so I also included that.  

Used the Original files and cdburgess's spring adjustment modification
