A mini bubble cube candle 42 mm on every side: eight round bubbles, two by two by two, the small sister of the viral 27-bubble cube.

Made with the hugging-shell mode of our silicone mold maker: print the base with the cube fused onto it and the two shell halves, pour about 130 ml of silicone, and the flexible mold that comes out peels off every waist. Small rounded fillers close the gaps between the bubbles, so it casts solid, with no tunnel through the middle.

Small and quick to pour, so it suits wedding favours, gift boxes and market bundles where you sell three or six in a set. The zip carries every printed part, the cube master as its own STL, the tool's own print-settings sheet and a recipe file for the generator.

What you need

4
  • About 152 ml of silicone (mix it in one batch)
  • About 48 g of pillar wax per candle: each cast is 53 ml
  • Steel binder clips, tape or a hot glue gun
  • A primed tealight-size wick, about 50 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 152 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

How big is the mini bubble cube compared with the bubble cube?

It is 42 mm on every side with eight bubbles; the full bubble cube is 61 mm with 27. The mini uses about a third of the wax, so it is the one to pour in batches for favours.

Can I make several mini bubble cubes at once?

Make the silicone mold two or three times from the same printed parts: each mold takes about 152 ml of silicone and then casts as many candles as you like. Pour them one after another while the wax is hot.

What wick suits the mini bubble cube candle?

A small tealight-size wick. The cube is only 42 mm wide, so a pillar wick would tunnel through it too fast and smoke.
