Aurora A3 Inductive Z Sensor Mount

This is an inductive sensor mount for the JG Aurora A3 printer.

Replaces the nylon standoffs under extruder heatsink.

Used ABS due to proximity to the heater elements.

*UPDATE:* Had my original mount break on me due to some vertical forces from the sensor running in to things (and bumping it up too many times). Created V2 that is a little beefier and printed with 50% infill.

*SECOND UPDATE:* I've switched from using this mount as I think it is too close to the hot end (even printed in ABS) and generally too thin. I get best (most consistent) results from the sensor when it is as close to vertical as possible ... and this mount just could seem to handle that.
