Case for RAMPS+Mega board to fit a 80mm fan. The case has thin walls and bottom (1.5mm). Top cover is 2mm thick. It has openings for the power cables, the bed and extruder resistors, and the usb cable. The top fits just right for most PLA materials we have tried. If it does not fit exactly, the top can be rescaled by 1% or so and re-printed (just takes a few mins).  There is also a cover to be used in place of the fan when storing the board, to protect it from dust.
