MPMD Optical Sensor / Endstop Alignment Jig

I wanted to align my Monprice Mini Delta's optical sensors as close to identically as possible. So I designed this jig to fit into the aluminum extrusion at the top of each tower, while still allowing wires to be run behind the sensor.

This jig aligns the optical endstop sensors to 40mm from the top of the aluminum extrusion, which is approximately the maximum height that the endstops will still work at. STEP files included in case anyone wants to remix this.

If you use this, please post a Make! I didn't want to disassemble my printer and have to tune it all over just to take pictures.
