Im looking for a source of the plug and pins that Lulzbot use for connecting the head to the printer (the plug with arrows for alignment on it) I think lulzbot sell the pins but im also after the plastic bit that holds the pins does anyone know what this part is ie molex ??? any help appreciated/
Look up the bom from the product page. The parts likely came from digikey
The black plastic plug housing is a 16 pos Molex 22552161 connector (Lulzbot ref EL-MS0251)
