# Custom cookie cutters, stamps and embossers

> Describe a shape or upload a sketch and get a cookie cutter with a sharp blade and comfortable flange, ready to print in PLA or PETG. STL, 3MF or G-code for your printer.

Cookie cutters are the classic quick print, and the classic thing nobody wants to model. Describe the outline (or upload a drawing), pick the size, and SpeakCAD generates a cutter with a 0.8 mm blade, a pressing flange and optional embossed details.

## Anatomy of a good cutter

- **Blade:** 0.8 mm wide (two extrusion widths) and 12 to 15 mm tall cuts cleanly without bending.
- **Flange:** a 4 to 5 mm wide rim 2 mm thick at the top gives you something to press on.
- **Depth stop:** an optional inner ledge keeps the cut depth consistent.
- **Draft:** a slight taper on the outside face helps the dough release.

## Stamps and embossers

Raised text and lines 1 to 1.5 mm high work well for fondant and polymer clay. Text is mirrored automatically when you say it is a stamp so the impression reads correctly.

## Food safety notes

Print in PLA or PETG with a clean nozzle, avoid dyes of unknown origin, wash by hand and consider the cutter a short-lived tool since layer lines trap moisture. Food-safe epoxy coating is an option for keepers.

- A round clay stamp 40 mm diameter with the letters ‘MK’ raised 1.5 mm, mirrored so the impression reads correctly.

## FAQ

### Can I use my own drawing?

Yes. Attach a clean black-on-white outline (PNG or JPG). The AI approximates the outline with a polygon and asks if a simplification is acceptable.

### What size can a cutter be?

Anything that fits your bed. Very large cutters (over 150 mm) benefit from a taller flange to stay rigid.

## About SpeakCAD

SpeakCAD is the most intuitive CAD for 3D printing, made for people who own a 3D printer and need a part that fits something they have: tap a face and type a size to shape it with simple tools, or describe it to the AI, on your phone or computer, and download a print-ready STL, 3MF or G-code sliced for your printer.

SpeakCAD works inside ChatGPT and Claude as a plugin (an MCP server): ask the assistant for a part with its measurements and SpeakCAD's own CAD AI designs it, shows it in 3D in the chat and hands over a print-ready STL, 3MF or G-code sliced for your printer.
