Egg Box is smartly designed and can only be manufactured by 3D printing. It is designed keeping in mind the pros and cons of stereolithography.

Egg Box is to be used by rotating the inner eggshell using your thumb as you hold the outer shell around your palm.

Printer: Ultimaker 2+ Material Used: Generic PLA Layer Height: 0.1 Infill: >40%

Supports were generated by Cura software. A small plier and paper cutter should be enough to clear out the supports after printing. Be careful in clearing the inner supports as the inner eggshell is weaker than the outer shell.
