Hi all, I thought I would share: I broke off the little magnet-sensor for the Z-height endstop on my MM2, and seeing that no one in the world except for RepRapDiscount sells those sensors, I had to order 3x just to fix the 1x I broke. No worries, except that the mounting plate did not fit the new sensor. Here is an .STL and Fusion360 file to adapt the sensors found here: http://www.reprapdiscount.com/electronics/18-set-hall-endstops3-pieces.html All you need is some M3x12mm screws to go through the holes (no nut needed unless you want it to be very secure). Also had to solder a new connector wire since the old sensor had them hardwired. Also needed to replace the magnet from the old sensor with the shipped ones as they are stronger and the one I had installed was facing the wrong way.
