Triwizard cup (Pohár tří kouzelníků/Přenašedlo) - Harry Potter

Edit:

Many people are having problems with printing the holds and to be honest the aren't really suitable for printing the way the are. If you are using PrusaSlicer, you can cut the holds in half and print them this way for a print without a bad looking supported side.

I haven't tested this idea myself but I thought it might help someone.
