Use as a backflow incense burner (smoke collects around the bottom of the cauldron) i would recommend a rubber washer between the incense and also PETG over PLA if you have a way to print it. Rubber washers ---> https://a.co/d/cpL7cCn At the bare minimum a metal washer (outside diameter= 5/8") should be used to keep from melting the plastic.

Can also be used to hold a tealight candle for ceremonies/decoration. There is a version with overflowing bubbles, and a low poly version (the one you see in the pictures of it working).

Enjoy :)
