Ancient column candle mold

Important note

Do now use PLA, something like PETG should work. Beeswax has a melting point at of 62-64 °C so it should be fine to use PETG if you will not overheat wax.

Also in my experience beeswax not sticking too badly to PETG.

I suppose you can use TPU, but hard plastic works fine for this.

Use decent amount of walls, you don't want for accidental wax leakage behind the walls into infill (ask me how I know)

How to use

Mold assembly

Cut a wick couple centimeters longer than mold height. Tie a knot on the on end of the wick. Pull it through “Bottom” part hole in such a way so knot will be in indent:

Assemble mold “Sides” around the “Bottom” and put “Rings” on it to keep mold together:

Next take “Wick holder”. Pull wick through bigger hole, put holder on top of the mold and then tighten wick slightly, pulling into slit. Fixate it with couple drops of wax or in other way:

If you pre-wax your wick, than you don't even need to additionally fixate it in place, it should hold by itself.

You can also put couple drops of wax on wick knot on the bottom of the mold to make sure there will be no leakage, but in my experience it is not required. 

Now you ready to pour molted wax in.

Melting & pouring wax

Full mold volume is ~180 cm^3. Final candle from bees wax weight ~140g, so you need to melt something like 160-180g of wax to feel mold fully.

Melt your wax and then keep it out of the heat mixing until it start solidifying. It guarantee that it's temperature is safe for plastic. 

Alternatively you can measure it's temperature. Glass transition temperature for PETG is around 85 °C, so wax should be cooler that that.

Carefully pour wax in mold. After some time you may need add more max to compensate for wax shrinking.

Left mold for some time, to be sure for next day.
