NEW MODIFICATION, bigger columns, centered holes of screw, although I haven't modified the x-carriage, I've added it to make everything easily modifiable only for coherence's sake. Based on Mk8 Extruder mount for Prusa i3 Rework by inornate - found at http://www.thingiverse.com/thing:835475, this is the most challenging part, and the support has a robust hole for an inductive sensor: NEMA 17 stepper motor is a stepper motor with a 1.7 x 1.7 inch (43.2 x 43.2 mm) faceplate, found at http://reprap.org/wiki/NEMA_17_Stepper_motor. Inductive Sensor 18mm (DC 6-36V NPN NC 5mm Inductive Proximity Sensor Detection Switch LJ18A3-5-Z/AX), like https://www.amazon.com/Inductive-Proximity-Sensor-Detection-LJ18A3-5-Z/dp/B008MU1GEY.

I've emphasized robustness and added fan support.
