Foam lemons found at dollar store, used CAT5 wires brown and striped blue, the pins are 18 ga stainless steel.
Print on high if going smaller then 3cm. (the size that the lemon cores are) Eye should always be printed on High settings as it is small
Dual Extruders can combine part1 and part2 then print and glue the eye in.
