Cookie Cutter Generator

Draw any shape or upload a silhouette, and get a cookie cutter you can 3D print. The outline is traced right here in your browser, turned into a cutting wall with a brim, and saved as an STL or 3MF. It is free, there is no signup, and nothing is uploaded.

How to make a cookie cutter

  1. 1

    Draw or upload

    Draw with Fill shape, Polygon or the brush, start from a sample, or upload a PNG, JPG or SVG silhouette.

  2. 2

    Check the outline

    The green line is the edge your cutter will follow. Use the eraser or brush to tidy it.

  3. 3

    Set size and wall

    Pick the cookie size, wall height and thickness. Turn on the imprint stamp for faces and details.

  4. 4

    Download and print

    Save the cutter (and stamp) as STL or 3MF and print it brim-down. No supports needed.

Print settings that work

These are safe starting points for a cutter from this tool. The defaults (1.2 mm wall, 15 mm height, 4 mm brim) are made for a 0.4 mm nozzle.

MaterialPLA or PETG. PLA is fine for cutting cookie dough at room temperature.
Nozzle and layers0.4 mm nozzle, 0.2 mm layer height (0.12 to 0.16 mm gives a smoother wall).
WallsAt least 2 perimeters. A 1.2 mm wall prints as 3 clean lines with a 0.4 mm nozzle.
OrientationBrim on the build plate, cutting edge up. No supports.
InfillDoes not matter much: the wall is thin enough to print solid.
Imprint stampPrint plate-down, lines up. Same settings as the cutter.

Is a 3D printed cookie cutter food safe?

A cookie cutter only touches raw dough for a moment, which is one of the better uses for a printed kitchen tool. Use a food-safe filament and wash it after each use.

Layer lines can hold bacteria: tiny grooves between layers trap dough and are hard to clean. Wash by hand in warm (not hot) soapy water, dry it well, and print a new one when it gets worn or hard to clean. Most printed plastics, PLA included, can warp in a dishwasher.

This is general guidance, not food-safety certification. Check what your filament maker says about food contact.

Good to know

  • A cutter follows one outer edge. Holes and lines inside your shape are not cut out; turn on the imprint stamp to press them into the dough instead.
  • If your drawing has several separate pieces, only the biggest one becomes the cutter. Join the pieces with the brush to keep them.
  • Very thin parts (under about 3 mm across at your chosen size) are hard to push dough out of. Thicken them before you print.
  • Uploads work best as a dark silhouette on a light background or a PNG with a transparent background. A busy photo will not trace cleanly.

Want the whole thing in 3D?

A cookie cutter keeps only the outline. To turn a drawing or photo into a complete 3D model (a figure, an ornament, a toy), our AI generator builds one from a single image. It uses credits; this cutter tool is free.

Frequently Asked Questions

Yes. It runs in your browser, needs no account and uses no credits. You can download the cutter and the stamp as STL or 3MF as many times as you like.
You print a cutter with the brim on the bed, then turn it over to cut. Turning it over flips the shape, so the tool mirrors the model first and the cookie comes out the way you drew it. This matters for letters and one-sided shapes. You can turn mirroring off in the settings.
No. A cutter follows one outer edge, so the tool keeps only the outer outline of the biggest shape and tells you when it dropped something. Holes and inside lines can go on the optional imprint stamp, which presses them into the dough.
It is a second part: a flat plate that fits inside the cutter, with raised lines that follow the details inside your shape, like eyes, buttons or a smile. Cut the cookie, then press the stamp into it. Draw details with the eraser (white lines inside the black shape).
The size you set is the longest side of the cookie itself; the brim adds a few millimetres outside it. For the wall, 0.8 to 1.2 mm cuts well and stays strong with a 0.4 mm nozzle. A wall height of 12 to 15 mm suits most rolled dough.
PLA is fine for cutting cookie dough at room temperature. Use a food-safe filament and wash it, since layer lines can hold bacteria. Treat a printed cutter as something you replace once it gets worn.
It is better not to. Dishwasher heat can soften and warp PLA and many other filaments. Hand-wash it in warm, not hot, soapy water and let it dry.
Yes, if it has a clear silhouette. Upload a dark shape on a light background, or a PNG with a transparent background, and adjust the trace threshold until the green outline looks right. To turn a drawing into a full 3D model instead of a cutter, try Image to 3D.
