Parametric cylindrical candle mold

I had some wax, and wanted to make some candles. I wanted to be able to pick the size, so a parametric design seemed like a good idea. I also thought a 3 part mold would be easier to remove than a 2 part mold, so I came up with this. Pick your size, and customize a mold for yourself. Print 3 parts of the mold. The top of the candle will be at the bottom when you are filling it. Cover the inside with some cooking oil, or mold release. Snap the parts together, with the wick in place. Use a rubber band or tape to hold the parts together. Follow normal candle making processes to melt the wax, pour the candle, keeping the wick tied to something at the top (which will be the bottom of the actual candle when it is done). Stay safe, don't overheat the wax, etc. Google for proper instructions on how to do that. I have had good luck using regular PLA with beeswax.
