Custom stamp maker

1. Pick what it's for: an ink stamp, a clay or pottery maker's mark, a cookie stamp or a wax seal. Each sets a good depth, shape and handle.
2. Type the text (a name, “Handmade by”, a monogram) or pick a logo: an SVG, or a PNG or JPG with dark shapes on a light background.
3. Set the size, then download the stamp and its handle as STL or 3MF.

The design is mirrored for you, so the imprint reads the right way round. The small preview shows how the imprint will look.

• Ink: a flat face and lines at least 0.8 mm wide; fine serifs and hairlines won't pick up ink evenly. Bold fonts work best.
• Clay and pottery: a raised design presses a clean mark into leather-hard clay. Dust the stamp with cornstarch or a little oil so it lets go.
• Cookies: bold shapes and a deep relief (3 mm). Press into rolled dough, and chill the dough first so the pattern keeps its edges in the oven.
• Wax seals: the design is cut into the face, so it stands up in the wax. A long handle keeps fingers away from hot wax; chill the seal on an ice cube between uses so it releases cleanly.

• Print the stamp face up: the design is then the top layers, crisp and smooth. Fine layers (0.12 mm or less) give cleaner edges.
• Print the handle standing on its knob, as laid out, then glue its peg into the socket on the back of the stamp.
• For a two-colour stamp, the 3MF keeps the design as its own part.

3D printed stamps aren't food-safe in the strict sense: layer lines can hold dough and bacteria. Use PLA or PETG, wash it straight after use, or cover it with food-safe film. The same goes for cookie cutters.

Want the text raised on an object instead, like a sign or a keychain? Use Text to STL. To put it on a model you already have, use Add text to STL. Cookie cutters are in SVG to STL.
