A ribbed dome candle 76 mm wide and 50 mm tall: half an egg with 24 rounded ribs running up from the foot and fading into a smooth crown, where the wick sits.
Made with the hugging-shell mode of our silicone mold maker: print the base with the dome fused onto it and the two shell halves, pour about 168 ml of silicone, and the flexible mold that comes out peels off the ribs a rigid mold would lock on.
Low, wide and steady, it burns for a long time and looks at home on a coffee table or in a bathroom. Pour it in oat, sand or white. The zip carries every printed part, the dome master as its own STL, the tool's own print-settings sheet and a recipe file for the generator.
Shown as a 3D render of the printed mold parts pulled apart around the master, not a photo.
Print the base, which has the master already fused onto it, and the two shell halves. No supports.
Stand the shell halves on the base around the master and hold the seams shut with steel binder clips. The seats for them are built into the shell.
Tape the outside seams or run a bead of hot glue along them, because silicone finds every gap.
Mix 191 ml of silicone in one batch, pour it into the open top in a thin stream, and fill level with the rim.
Once it has cured, unclip the shell, lift it off and peel the silicone off the master. That silicone is your mold.
Set the silicone back in the shell to keep its shape, and cast into it through the opening the base left.

The ribs run from the foot to the crown, so at the sides of any split their flanks face the way a rigid half would have to pull, and they lock it. Flexible silicone stretches over them and lets go.
One wick sized for a 70 mm candle, or two smaller ones set 30 mm apart. A wick that is too small tunnels down the middle and leaves the ribs standing.
About 138 g of pillar wax per candle, from a mold made once from about 191 ml of silicone.
