Snap-Together Easter Egg

After failing to find any printable Easter eggs in the usual snap-together style, I spent a good amount of time developing the perfect printable Easter egg. This one snaps together with a reasonable amount of tension, is not overly hard to open, and prints quickly with no supports.

I've provided STL files in 2 sizes; a normal size (25mm radius) and an extra large size (50mm radius), and I've also provided the freecad project for the large one in case you want a different size. It shouldn't be too hard to modify to a different scale if you want, just keep in mind that you'll want to maintain the same wall thickness. If you just scale the STL you'll end up with a very thick egg that will (probably) be absurdly difficult to open.

I've mainly printed these in PETG. In theory they could be printed in PLA as well but I would imagine the tension may be a little different.

Happy hunting!
