Prusa i3 box for Megatronics v3

thingiverse

This is a box to host Megatronics v3 board (mine is rev. E). The box is designed to be mounted on the back of a 6mm aluminium frame using existing holes. Features clips to keep stepper and other cabling in place clips on cover to keep fan cable in place three large entry windows on bottom for air and cable enter almost open back for cooling 50x50 fan mount (to cool XYZ stepper driver and power mosfet) with spacers to avoid contact with cover open top to let air circulate Known issues There is a cut on top-left because I have a stabilizer rod (I strongly suggest to add stabilizers, the one I designed is here: http://www.thingiverse.com/thing:624383 ). You can keep it as an exit/entry point for cables No windows / holes for leds (they're so bright you'll see them anyway :) ) Instructions Printed at 0.35 layer height, 1mm perimeter, with 0.5 nozzle Cover clips for fan cable needs you cut support to route cable in Vitamins 4 x M3x10 screws to mount the board 2 x M3x20 screws with nuts for fan 3 x M3x10 screws to mount to the frame 4 x M3x10 screws to lock cover, better to use screws for wood. Probably the best thing here would be to use brass press fit inserts. Depending on the tolerance of your printer, please check holes/screw mounts before mounting everything!
