Golden Egg in a Cup: Golden Ellipsoid

Golden Egg in a Cup: Golden Ellipsoid (Major Axis: 40mm) Try spinning the egg a few times; you might get a surprise! It stands upright! The Design Story Someone asked for a golden egg, and it's super easy to design but not so easy to print. You need either dissection or support, which can be tricky. To keep its aesthetic appeal and avoid wasting filament, I put the egg in a spherical cup. In a playful twist, I also converted the bottom part into a cup. Now we have a two-headed cup, and the egg can fit in either one of them. The next challenge is to print it all in one piece. It's theoretically possible to print everything together and then separate them after printing. However, when the cap is placed horizontally on top of the cup, it can be hard to pry off. But it works if you have a thin blade and some patience – wear gloves! I decided to slice the cap at an angle for easy separation. Now, if you want, you could try printing that file in one piece. To save time and hassle, please consider separating the cup and cap when printing. To make it more playful, I created two different cups. The one with a slant top can accommodate both caps because of their interior shapes. The egg should come off easily after a few twists. If necessary, use a pair of pliers (seen in pictures). Among the Files 1. Two versions of cups with an egg. 2. Two versions of caps. 3. An all-in-one design that actually works. Printing Parameters In my experiments, the egg spins well at 10% infill and 0.15mm resolution. Please consider increasing the infill to 20-50% for a heavier feeling.
