mini height sensor board - Differential IR Z probe mount for E3d Chimera

I designed this so I could use the mini height sensor board with my E3d Chimera and duet electronics. Sensor link below.

I printed it in ABS to make it a bit more heat resistant as it's pretty close to the heat block, It mounts on the front of the fan.

When homing the hotend ends up being about 1.9mm away from the bed so I modified the G31 command in the config file to G31 Z1.9 P500
This way when it's homing the hotend will be 2mm away from the heatbed but once the print starts the hotend will be at the correct height.
