Inspired by Russian Fabergé eggs, many of which could open up to reveal a surprise inside.
This egg features a maze that must be solved to access the inner compartment.
Use a 0.4mm nozzle and a layer height less than 0.2mm
There are two versions:
In one the trim is designed to be printed separately and then snapped into place.
The other all-in-one version comes in only two files. You can change colors at specific layer heights or paint-on materials if you have a multi-color printer.
