renegade_geek posted a set of Pumpkin Faces on thingiverse for the EggBot. They’re cleverly arranged in layers so that you can hide and show the different eye, nose and mouth options.
A collection of separate eyes, noses and mouths, each set on its own layer, for a customized jack-o-lantern/ghost face to be printed with the Eggbot. These were made to print on ping pong balls. You may need to adjust for eggs and other less regularly shaped items. I have included a “faces menu” PDF so that you can clearly review your choices. This was really helpful in a classroom situation.
