I couldn't find any cauldrons that had the aesthetic I was looking for so I designed this toy cauldron in Blender inspired by the Magic Mixies. I left out some details and embossing as my blender skills are still quite basic. One detail I included was a small flat gem for the cauldron that can be printed in a different material and attached to make them a little more unique. For our daughter's recent birthday I printed a whole bunch of them with different colours as prizes to search for in a scavenger hunt. I found that they make great dice boxes and as part of the scavenger hunt each cauldron held a 12-sided die which the child would roll to decide which cauldron to look for next.

I printed the cauldrons with 0.20mm layer height, 15% gyroidal infill on an Anycubic Vyper. The gems I printed separately with 0.10mm layer height and using the ironing feature in Cura.

The blender file is attached for anyone who would like to remix!
