I created this because i got the wrong mount from the L-Cheapo creator. Its a full replacement of the back side of the RepRepPro Mendel Mono x-carriage.
I added also a version for an additional capacitive LJC18A3 Z-Probe (or any other probe with 18mm diameter) which I use for auto bed leveling.
The fan is not directed to the focal point anymore (it was in the original mount for a reason). I highly recommend an additional fan (like the one for your PLA prints) during the cutting, that is directed to the focal point of the laser.
