This is a design for a gumball coin mechanism used for a greeting card. The gumball machine is cut from cardboard and clear plastic. The simulated coin mechanism makes for a realistic gumball machine with twist handle and flap door.
Printed in PLA at 0.1mm layers
200C extruder and 50C bed
Print at least 4 at a time to keep layers from being distorted by excessive time of extruder in one place. I spray painted the coin mechanisms with shiny silver paint.
