Will you be able to find the surprise in the egg? Game rules: print at least two eggs, one empty and one with the prank (the prank is the rabbit showing its bottom and doing a big poop). Put a chocolate egg or a small gift in the empty egg, present them to a family member during the holiday lunch and observe their reaction. Will they find the poop or the chocolate? Okay, very funny, but: how do you print it? It's very simple, if you have a Creality K1 Max, just load the gcode I use! Otherwise, import the stl models into your preferred slicing program and print it, you'll get an egg split into two parts. Once printed, remove it from the bed and close it. The first time might be a bit hard to open and close, just open and close it a few times to make it smoother. If you prefer, you can remove a very thin inner layer by gently filing the inside of the top part of the egg, but with my printer just snapping it and opening it a few times will work great without any post-processing. Easy! Do you need supports? NO! They're not needed, you don't even need to add a brim, glue or adhesion methods (I've tested with my K1 Max printer). To sum up: print without supports, no need for glue, no need for adhesion methods, print two eggs to play with someone. Have fun!! And yes, you can sell the renders and 3D prints for commercial use, but you can't distribute the digital 3D model file because I'm the author and I prefer to personally control the distribution of the digital file.
