Yoshi Egg Sign I created to put on my son's bedroom door, it was his idea, I created this design in OpenScad and printed it using the Prusa's colorprint that allows you to change colours after a certain layer.
This used 3 colours, white base, green for the egg and black for the border.
Printed using prusa's colorprint (http://www.prusaprinters.org/color-print/) to swap out colours on certain layers, used white for the base, then green and black.
Easy print, should allow reducing size to about 50% and still maintain enough of layer separation for multi-colour.
Printed in PLA but should be ok for any other material.
Created in OpenScad
Created in OpenScad using the surface method to import a image created in Gimp.
