A bubble pyramid candle 66 mm square at the base and 50 mm tall: nine bubbles in the bottom layer, four in the hollows above them and one on top, stacked the way cannonballs sit.

Made with the hugging-shell mode of our silicone mold maker: print the base with the pyramid fused onto it and the two shell halves, pour about 154 ml of silicone, and the flexible mold that comes out releases every bubble. The middle is filled solid, so the candle comes out as one piece with no hidden holes.

A low, stable candle that looks good on a coffee table or a bathroom shelf, and a nice change from the cube. The zip carries every printed part, the pyramid 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.

What you need

4
  • About 177 ml of silicone (mix it in one batch)
  • About 91 g of pillar wax per candle: each cast is 101 ml
  • Steel binder clips, tape or a hot glue gun
  • A primed wick about 70 mm long

How to cast it

6

  1. Print the base, which has the master already fused onto it, and the two shell halves. No supports.

  2. 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.

  3. Tape the outside seams or run a bead of hot glue along them, because silicone finds every gap.

  4. Mix 177 ml of silicone in one batch, pour it into the open top in a thin stream, and fill level with the rim.

  5. Once it has cured, unclip the shell, lift it off and peel the silicone off the master. That silicone is your mold.

  6. Set the silicone back in the shell to keep its shape, and cast into it through the opening the base left.

Questions about this design

Where is the wick in the bubble pyramid candle?

Straight down through the top bubble, the highest point, to the middle of the base. Pierce the silicone at the top of the top bubble with a wick needle, or push a heated wick pin down through the set candle.

Is the bubble pyramid a good candle to sell?

It is a fresh take on the bubble trend, low and stable, so it ships well and sits safely on a table. It takes about 91 g of wax, which keeps the material cost low for a market or a small shop.

Does the bubble pyramid mold trap air between the bubbles?

No. The tool checked the cast for air pockets and found none: every bubble has a way up to the pour opening. Tap the mold on the table after pouring so small bubbles in the wax itself rise out.
