This adaptor uses the factory M3 holes in the back of the (Sanguinololu based) Solidoodle printer to mount an Arduino Mega and RAMPS. An 80mm cooling fan can also be fitted to keep the resettable fuses and stepper motor drivers cool. This mount also offsets the electronics to provide clearance for the filament spool.
Print at high infill for strength.
Assemble as shown in photos. You may need to elongate some of the holes to get them to line up with the Solidoodle holes, they are a tight fit.
Fan on RAMPS is highly recommended if you have a fast heating bed that draws a lot of current. Without cooling the resettable fuses can trip causing a restart to be required.
