Free during the launch. Sell what you cast.
Designing, previewing and generating kits are free for now. A per-kit price will come later; everything you download today stays yours.
- 9 STL files generated from your exact parameters: 6 mould parts plus their variants
- README with silicone and concrete quantities, print settings and steps
- Print as many copies as you need for your own workshop
- Personal and commercial use of the cast objects, no expiry
- Download link right away, plus a copy by email
No card, no account. The paid version will come later.
Cheaper than a ready-made mould, more flexible than a fixed STL.
- 01
Fixed-size STL kits
Sold at a similar price, but the wick socket, drainage, dimensions and relief cannot change — and commercial use often requires a subscription.
- 02
Ready-made silicone moulds
Typically $16 to $67 for one size and one texture. A kit lets you make the mould you want, in the silicone you choose.
- 03
Drawing it yourself
Hours in CAD for a formwork that may leak, a master that floats and a silicone estimate that is off by a cup.
The licence in one paragraph
Each kit is licensed to you, the user. Print it as often as you like for your own use. Sell the candles, planters and trays you cast from it — personal and commercial use of castings is included, forever. Do not sell, share or publish the STL files or the printed mould parts.
Questions makers ask before their first kit.
Short answers. The guides go deeper on silicone, formwork and casting.
Still unsure? Write to hello@mouldery.com.
What exactly is in a kit?
A ZIP with nine STL files — master model (plus a plain variant), one-piece formwork (plus a two-half variant), base plate, rigid core, bridge, wick centring tool and a reference model of the finished vessel — plus a README with the hardware list, silicone and concrete quantities, print settings per part and the step-by-step.
Which 3D printer and filament do I need?
Any FDM printer with a 220 × 220 mm bed covers the current presets. PLA works for every part; PETG if your workshop gets warm. The formwork prints upright with a 0.6 mm line width and two perimeters, no supports on any part.
Which silicone should I use?
A pourable mould silicone of Shore A 15 to 25. Tin-cure (condensation) silicone is cheaper and tolerant with printed masters. Platinum silicone lasts longer but can be inhibited by some prints: seal resin masters with spray paint or acrylic sealer and test on a scrap print first.
How much silicone will I need?
Your README gives the computed volume plus a loss margin, in millilitres and grams. For an 80 mm candle jar it is roughly 430 ml computed, 470 ml to buy. Tray presets need less, deep planters more.
Do I need draft angles?
No. The vessel is released by deforming the silicone block, and the inner sleeve peels out of the cavity once the rigid core is removed. Straight walls and light undercuts demould fine. The core itself carries 1° so it slides out of its sleeve.
Can I sell what I cast?
Yes. Personal and commercial use of the cast objects is included with every kit, with no expiry and no subscription. What you may not do is sell, share or publish the STL files or the printed mould parts. See the licence.
Your next vessel is one evening of printing away.
Configure it in the studio, print the kit tonight, pour silicone tomorrow.
