This is a fun concept. I tried printing this and there are a couple of issues:

• The diameter of the top and bottom are not the same, but I was able to fix it in the slicer.
• There's no way to fill it effectively. I added a hole in one side for filling.
• There's no way to remove the ice ball effectively on the dish side. I tried TPU and I think the walls are too thick.
• There are artifacts in the sliced model which appear to be from inconsistent surfaces.

How the heck do you fill it to come out as one singular orb?

can you make a holder for it too so it doesnt break apart when you place it down

Very nice! What material/settings did you use?
