Allows you to mount a Smoothieboard to your Rostock MAX's electronics bay door. The board is mounted with the electronics and LEDs facing outward, and is stood off from the door to accommodate all the connectors. The door hanger can be screwed into place, but it doesn't have to be. The two top standoffs on the mount are keyed to be force-fit into the door hanger. You will need four screws and matching nylon locknuts to fasten the board to the mount. The parts are thin and fragile in places. I've beefed them up by adding some strakes, which seems to help a lot, but they will break if you put too much force on them. Please be careful, and remember to wear an ESD (grounding) wrist strap. In particular, be cautious when plugging in or removing the USB cable. Hold onto the mount to stabilize it while you do this. Otherwise, you may shear off the top standoffs! Inspired by mhackney/EclecticAngler's mount.I recommend printing with 3 loops, 33% infill on the mount, and 25-33% infill on the door hanger. Print with 50-100% infill if you want it stronger. Support is not necessary. Use layer cooling fans if you have them.
