This enclosure is designed to house the RAMPS electronics for RepRap, a 50mm fan for cooling the Pololu stepper drivers and mosfets, and an optional LCD display in the lid. It should work with v1.1, and 1.2 RAMPS, and other shields designed for the Arduino MEGA that have the 2" x 4" footprint.
Side mounting clamps are designed to attach to 5/16" or M8 threaded rod, with plastic ties.
Cable access is through the front of the enclosure, but there is also a hidden slot built in to the side wall, in case there are shorter cables that cannot make the long way around to the front.
Can be mounted almost anywhere, but my preference is the back left corner of the machine (Prusa).
