Silicone mould box generator: from your 3D model to a printable mould kit
Load an STL, 3MF or OBJ and the app builds the kit around it: base, walls held by binder clips, a two-part block with registration keys. Or make direct moulds for soap, resin and candles, and concrete pot moulds.

How it works
- Load your model, or choose a mould without a model.
- Pick open box or two-part, the shape of the box and how much silicone goes around.
- Download the pieces and print them flat or upright: no supports.

Tips
- PLA is fine for the mould box. Seal the walls with a thin bead of hot glue or plasticine at the base if your silicone is very runny.
- Use a release agent on the printed parts and between the two silicone halves.
- Silicone volume is shown under the preview: mix about 10% more.
- For concrete pots oil the shell and core, fill the core with sand to weigh it down, tap to release the air.
Questions
Which file formats can I load?
STL, 3MF and OBJ. Very heavy models are simplified in the browser; nothing is uploaded.
What if my model is not a closed solid?
It still goes in the mould, but it cannot be joined to the base: print it separately and glue it, or repair the file in your slicer.
How do the walls stay together?
They slot into a groove in the base and have flanges on the split: two binder clips per side hold them tight.
Is it free?
Yes. Vaseverse is free, with no account and no ads.
