Mold Craft (3D PrintCraft)

What is Mold Craft (3D PrintCraft)?

Mold Craft turns a 3D model into a two-part casting mold. You upload a closed model as STL, OBJ, PLY, 3MF, GLTF or FBX, and the tool subtracts it from a block, splits the block along a parting plane you can move, and adds tongue-and-groove alignment, grooves for a strap, a pour sprue, an air vent, a wick hole and a notch for prying the halves apart. The halves are shown in a 3D preview with the model inside, so you can spot undercuts before printing.

Material presets for wax, soap, resin, plaster, chocolate and caramel set the clearances and wall thickness. A form-fitting mode follows the model's outline instead of a plain box, which the site says roughly halves the plastic, and the mold weight is shown before you export. The tool also reports open or broken edges when a mesh needs repair first. The site's own advice is PETG for soap and wax, and using the printed mold as a master for a silicone mold when casting epoxy. Downloads are STL and 3MF.

Mold Craft is part of the PRO plan on 3D PrintCraft, a small Russian site: 99 RUB a week, 299 RUB a month or 1,990 RUB a year for all PRO generators, with a 3-day trial after sign-up and no card needed. The landing page is in Russian; the site says the interface is in Russian and English. It suits soap and candle makers and anyone who wants to cast copies of a model they already have.

What you can make

• Two-part molds from any model
