This design is based on the concepts I used for https://www.thingiverse.com/thing:5473481. But instead of using a squircle-based Loft surface for the top part I used a surface of revolution with an egg-shaped sweep curve. I don't know if anyone has created a mathematical definition for an egg shape (I guess different kinds of eggs have different shapes), so for this shape I used a curve made from 2 Bezier curves. And just like you'd do when eating a soft boiled egg, I whacked off the top to make an open container. Note that for printing I specified my slicer (SuperSlicer) to use "Fuzzy mode" for all outside perimeters. I did this to hide the imperfections regular perimeters would produce on the underside of the areas that have shallow slopes. These include the bottom 1/4th of the egg shape and most of the undersides of the 5 twisted feet. Fuzzy mode hides these imperfections quite well. Note that you have to be very careful when removing this part from your print bed. I used 15% triangular infill and it wasn't strong enough to avoid a few cracks when removing the part. So I'd suggest 100% infill and to use a thin scraper tool to free up each foot individually. This print completed in a little less than 11 hours using a print speed of 100 mm/sec and layer height of 0.203 mm.
