Arduino RAMPS 1.4 Prusa Support with fan

This is a support for RAMPS 1.4 and arduino on a Mendel Prusa.

It locates the whole electronics on the upper section of the printer.

It also features the possibility to add a 90mm fan to cool down the stepper drivers as well as a central filament guide.

The original model was printed in ABS with a 0.20mm layer height. Takes about 3h30 to print.

NOTE: The support for the fan has to be treated gently. I will reinforce the columns in a future revision.
