It's just a derivative, just three little change to mount it in a MendelMax.
Change:
-Endstop_holder : I take the "no support" option in the openscad file, and shortened the lenght because my coupler is bigger and hooked the endstop_holder...
-Frame_mount : I adjust the spacing to screw it on the Z motor on the upper frame, and modify the lower frame so it does not bother the motor when I mount it.
