A printable, reusable mold box for making your own silicone rose candle mold. The rose is printed together with the base, so there's nothing to glue or align: assemble the walls around it, pour silicone, and a few hours later you have a soft mold that releases every petal. A rigid two-part mold can't do this — the overlapping petals would lock the wax in. Silicone just peels off.
I've cast six rose candles in this mold so far, and it's still like new.
What's in the files
A round base with the rose master fused to it
Two curved wall halves that close around the base
Two clips that lock the halves together
Open top for pouring
What you'll need
About 80 g of mold-making silicone. I used a soft one: Shore 10A, mixing ratio 100 : 1.5–2.5 (base : catalyst), gel time 10–20 min, full cure 24 h, shrinkage 0.3–0.5%. Soft silicone peels off the petals easily.
Wax: 50/50 soy wax and paraffin. Pure soy wax is quite brittle and the thin petal edges can chip; paraffin makes them stronger.
Any wax colorant of your choice and a wick.
How to make the mold
Print the base and the two wall halves.
Close the two wall halves around the base and slide on the clips.
Mix the silicone with the catalyst and pour it slowly from the top over the rose until it's fully covered.
Let it cure for 24 hours.
Slide off the clips, open the walls and peel the silicone mold off the rose.
How to cast a candle
Melt the wax (50/50 soy and paraffin) and add the colorant.
Pour it into the silicone mold and set the wick.
Let it cool completely, then flex the silicone and pop the candle out.
The box is reusable: take it apart and pour a new silicone mold any time.

How the mold was made
You can design a mold box like this in any CAD program if you're willing to spend some time on it. I made it with 3dgenapp — it builds a silicone mold box around any STL in a few seconds, right in the browser, no CAD needed.
