About Mouldery

Why Mouldery exists

Makers who cast candle jars and planters in concrete already know the technique that works: print a hollow master and a frame, screw the master to a plate, pour silicone around it and inside its cavity around a rigid core, push the master out, then cast the vessel upside-down with its bottom open. It gives a crisp rim, a clean wick socket, no draft angle to think about, and a mould that lives in its own frame.

What did not work was getting that technique for the vessel you actually wanted. The kits sold for it come in a handful of fixed sizes, with a wick socket, a drainage hole and a relief you cannot change. Drawing your own means hours in CAD, and then a frame that leaks, a master that floats or a silicone estimate off by a cup. Mouldery takes the validated technique and makes every dimension of it a parameter.

What is free

Everything up to the files. The studio runs in your browser with no account: pick a preset, change the footprint (circle, rounded rectangle, tilted square, ellipse, polygon), the height, wall, cavity, wick socket, drainage hole and relief, and watch the capacity in ml and oz, the silicone volume and the concrete mass update as you go. The 3D preview shows the parts of the kit around your vessel. You can iterate for an hour and pay nothing.

What is generated after payment

When you pay, your browser rebuilds the kit at full resolution from the exact parameters of your preview, stored with your order and checked by a hash so the files match what you saw. The ZIP contains nine STL files (master and its plain variant, one-piece formwork and its two-half alternative, base plate, rigid core, bridge, wick centring tool, plus a reference model of the finished vessel), a README in English and French with the hardware list, print settings per part, the silicone and concrete quantities and the full step-by-step, and a kit.json with the same metrics for your own records. The download link is personal and does not expire.

Who it is for

People who cast vessels in concrete, Jesmonite or plaster and sell them or give them away: candle makers, planter makers, anyone who wants a tray with their own relief on it. People with an FDM printer and a kitchen scale, who would rather spend their evening pouring silicone than modelling a frame. And small production runs: the licence lets you sell what you cast without limit, and the Studio Pass, when it arrives, will let you generate as many kits as a product line needs.

Where the geometry comes from

The reference kit was rebuilt part by part in parametric CAD from a technique proven in the field, then checked: every solid valid, no interference between parts in the assembled state, silicone and concrete volumes computed from the actual geometry rather than estimated. The web engine reproduces that kit, and the guides on this site document the figures it relies on, from the 0.15 mm fit of the frame to the 70 g of lift on the core. Where a figure comes from a material datasheet or a supplier chart, the guide says so.

What is coming, honestly

No dates are promised for any of it. A feature is announced here when it ships.

• An annual Studio Pass with unlimited kit generations, for makers who iterate on a range. It is listed on the pricing page as coming soon, and that is what it is.
• A text pattern: a word or a short line engraved on the front face, next to the leaf and the geometric reliefs.
• 3MF export with named, pre-arranged parts, alongside STL.
• More vessel families, and previews rendered from the real geometry for every preset.
• Real feedback. The quotes on the home page are marked as examples until makers from the early-access cohort report back, and they will be replaced, not edited.

What we do not claim

No customer numbers, no five-star badges, no testimonials we did not receive. Mouldery is new, and the only claims on this site are the ones you can check in the studio, in the README of a kit and in your own workshop. If something here is wrong, write to hello@mouldery.com and it will be fixed.
