3D Printing
3D Cookie Cutter Generator
Turn an image, text or favourite shape into a cookie cutter that is ready for a 3D printer. The lines inside the image can become a stamp that presses the pattern into the dough, and everything is processed in your browser.

3D printed plastic is porous and is not designed for long contact with food. Use the cutter only briefly to cut dough, wash it by hand, and choose a food-safe filament if you can.
How to make a cookie cutter
- Choose Image, Text or Shape. For an image, pick a file, drag it onto the preview, or paste it with Ctrl+V.
- Check the cookie shape in the preview. Move the Light/dark threshold or turn on Remove plain background if the shape is not right yet.
- Set the cookie size and cutter height, then choose whether you want a pattern stamp.
- Download the STL or 3MF and print it without supports.
How to use the cutter and the stamp
- Roll out the dough to an even thickness and dust it lightly with flour so it does not stick.
- Press the cutter down, blade first, until it goes through the dough, then lift it.
- Press the stamp onto the cookie with the pattern facing the dough, either from inside the cutter before you lift it or on its own. Lift it straight up.
- If the dough sticks to the pattern, chill the dough for a while or dust the stamp with flour.
Printing tips
- Print with a 0.4 mm nozzle and 0.2 mm layers. The cutter and the stamp need no supports.
- Make sure your slicer does not drop thin walls: a 0.8 mm blade means two lines of a 0.4 mm nozzle.
- Shapes with lots of small curves are easier to use once Smooth edges is raised.
- For big cookies over 120 mm, raise Wall thickness so the cutter does not bend easily.
Food safety
- Use the cutter and the stamp only for raw dough, only briefly, and never to store food.
- Wash by hand with warm water and soap. Hot water and dishwashers can warp PLA.
- PETG or a filament labelled food safe is a better choice than ordinary coloured PLA.
Frequently Asked Questions
An image with a clear, fairly simple outer shape, for example black line art on a white background, a silhouette, or a PNG with a transparent background. The lines inside the image become the stamp pattern. A very wiggly edge is simplified, because dough cannot follow narrow curves.
The cutter cuts the edge of the cookie. The stamp is a separate plate with a raised pattern that is pressed into the dough, so the lines inside the image or text show on the cookie. The stamp is slightly smaller than the cutter, so you can press it from inside the cutter after cutting the dough.
The cutter is printed with its handle flange at the bottom and the stamp with its pattern on top, and then both are flipped when you use them. That is why the shape is mirrored on purpose, so the cookie and its text face the right way.
PLA and PETG are the most common. PETG handles heat better and is easier to clean, and some brands sell filament that is labelled food safe. Keep in mind that the layered surface of a 3D print has tiny gaps where dough can stay behind, so use the cutter only for raw dough, wash it by hand, and never put it in an oven or dishwasher.
Cookies are usually 40 to 80 mm. A height of 15 mm is enough for dough up to about 8 mm; for thicker dough, make the cutter taller. The size shown under the preview is the cookie size, and the cutter itself is slightly larger because of the wall and the handle flange.
The letters are grown with Cookie border width until they merge into one shape, then the cutter follows the outer edge and the letters become the stamp pattern. If they are still separate, raise Cookie border width or pick a bolder font.
Yes. The STL opens in every slicer, such as PrusaSlicer, OrcaSlicer and Cura. The 3MF holds the cutter and the stamp as two separate objects, so it is easy to delete or move one of them.
No. The image is processed in your browser, from reading the shape to the STL and 3MF files. The last image is stored in the browser on your device so you do not need to pick it again; click Remove image to delete it.
