About this 3D model
The holes for this mount should fit the Goofoo Nova and perhaps the PLUS ( I do not have that printer) We power the PI using a UBEC for powering servoes in RC. 40mm blower fan push air over a heatsink and back in the printer. This setup is running on our Goofoo Nova that are printing almost 24/7 with prototype printing.
