Treasure inside - Impossible Easter Egg

This treasure egg puzzle will really add to the Easter Egg Hunt fun! This apparently impossible egg remix has a coin compartment inside that will fit two coins up to 31mm in diameter (US 50 Cent piece) or up to 3 smaller coins (US quarter). Or it can also fit a bill folded square. Coins are a lot more fun.

Kids will know there is something in there and just have to figure out how to open it.

In this case I have uploaded just an assembly of the 4 parts instead of the individual parts. Too big a chance the wrong parts will be duplicated. If two of the parts with the coin compartment are printed there is a risk that an object shifting inside could lock the puzzle together.

Update: Cura 15.04.6 can split the assembly and allow you to print one part at a time. I have since uploaded the individual parts for easier printing on smaller printers. The titles have the number of times they are to be printed for a complete egg puzzle. Pay attention to what you are loading in you
