This is a mount for the RAMPS_1.4/Arduino Mega 2560-combination to controll the hypercube evolution. I made it opened, to avoid thermal problems. All you need is 3 screws M3x20, 3 screws M5x10, 3 hammernuts M5 and 3 of those 5 mm brass insert nuts for assembly. See fotos. I attach the FreeCAD-File for redesign. Allways have fun.
