Quick Exchange MK8 Extruder + Inductive Sensor Mount for PROXXON Tool Holder

I made this bracket to be able to plug an MK8 extruder into the PROXXON/Dremel Mount of the Mostly Printed CNC. It mounts and unmounts as quickly as the spindle or the laser, making tool changes easier.
This thing should hold many extruders (at least the MKx series) since it was designed to "hug" a NEMA17 stepper. It also features a bore for 12mm inductive sensors as a Z endstop.
All that is needed is a 20mm M4 bolt with a hex nut.
