A Christmas tree candle 84 mm tall and 72 mm across at the bottom tier: six layered skirts of soft, scalloped boughs, each turned a little against the one below, narrowing to a point where the wick comes out.
Made with the hugging-shell mode of our silicone mold maker. Every tier overhangs the one below it, and a rigid two-part mold would lock on those edges, so this is a silicone mold: print the base with the tree fused onto it and the two shell halves, pour about 176 ml of silicone, and the silicone peels off the tiers and closes back up for every candle.
Pour one in deep green, one in white, one in red with a little gold mica brushed on the tier edges, and you have a set for the mantelpiece, a market stall or a gift box. The zip carries every printed part, the tree master as its own STL, the tool's own print-settings sheet and a recipe file for the generator.

What you need
- About 200 ml of silicone (mix it in one batch)
- About 103 g of pillar wax per candle: each cast is 114 ml
- Steel binder clips, tape or a hot glue gun
- A primed wick about 120 mm long, and candle dye or mica if you want colour
How to cast it
- 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 200 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.
