my own creation of an item i saw in a youtube video of an incense fountain the top accepts a washer or two to buffer heat from cone incense this does require supports preferably tree supports.

yet another update v3 has u shaped troughs to contain stream better and no back plate and seems to work better recommend supports (i used tree supports)

3mf is of most recent best version in .4mm nozel size if other nozel sizes are wanted for direct printing feel free to message/comment the request and id be happy to upload another 3mf file for convenience.
