18mm Inductive Sensor Rear Mount

Use for mounting your inductive z-height sensor behind Mak-a-face's 3 or 4 bearing x-carriage for the following prusa i3 re-work style x-carriages:

This locates you inductive sensor behind the x-carriage and out of the way which is very nice and clean. It also helps balance the mass of the hot-end so that the CG of the carriage is more aligned with the belts.

Unfortunately this DOES limit your z-height on prusa i3 so look elsewhere for an inductive sensor mounted on the front side of the x-carriage if that is important to you.

For this design the sensor is clamped in the bracket, you no longer need the nuts to lock it in - BUT I like to position the nuts on the top of the bracket with them jammed together as a method of maintaining the vertical location of the sensor if you need to dis-assemble the x-carriage and do not want to lose fine-tuning of the z-stop height.
