So this is my very first design I'm uploading.

I played around with the Make my Vase Software and came up with the above design.

I works best with tree supports. Very easy to clean.

I tested it with a candle and it works 100%. It gathers the wax and (unless candle was put in skew) the wax doesn't drip off. The print got warm, but didn't warp or deform.

I used PETG. 

Enjoy!
