it is a remix of a egg in our fridge.
Print upright with support. I print with PrusaSlicer above thr print sheet (see  file "Egg3-60mm-voll.3mf" when you add a block to the print sheet, the egg can be placer above the print sheet)

Sizes:
25mm, 30mm, 40mm, 50mm, 55mm, 60mm, 70mm

Other sizes an be set by scaling on the slicer.
