This mod adds the ability to attach a 3D/BL Touch sensor instead of the 12mm inductive sensor. As it is a modular design (https://www.thingiverse.com/thing:2777161), the backplate does not have to be reprinted again. Height is adjustable to create the correct distance between the nozzle and the bottom of the platic part of the sensor (about 4mm).

The design makes use of those brass inserts to attach the screws.
