This adaptor uses the mill M3 holes at the rear of the (Sanguinololu established) Solidoodle printer to mount an Arduino Mega and RAMPS. An 80mm cooling fan may also be fitted to keep the resettable fuses and stepper motor drivers trendy. This mount also offsets the electronics to give 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've got a fast heating bed that draws lots of current. Without heating the resettable fuses can trip causing a restart to be required.
