These are some of the cracked pot weapons you can craft in elden ring. Namely the standard Cracked pot (in full and empty model, as you can put flowers in the wholed one or smth), fetid pot and the sleep pot.

Size (the tallest, the fetid pot) around:H8,5 cm x W8,5 cm x D11 cmH3.3inchx W3.3 inch x D4.3 inch

For printing: 0.2 layer height makes a fine result, but towards their top i would advise smaller. Also On the bottom you need supports, since it is like a ball. But you can't see those parts anyways.
