STL → Mould → Print

Turn any STL into a printable mould.

Turn your 3D model into a mould you can print. Get both halves with built-in alignment pegs, a pour hole and air vents, ready to print and cast.

How it Works

Drop in an STL (binary or ASCII), set the scale and pick which side faces up.

A rigid two-part mould, a silicone pour box, or both. Tune walls, keys, sprue and vents.

Preview, then download every part as STL files in one zip and start printing.

Adjustable parting line and plane tilt, with a shape-hugging or box outer shell.

Removable frame with cuts and slide-on clips so the silicone pops out cleanly.

Registration keys with fit clearance, plus a tongue-and-groove seal along the parting line.

Pour sprue placed where you click, a pour funnel and air vents at the highest points.
