Cookie cutter STL generator
Turn a drawing, a logo or a photo into a cookie cutter you can print tonight. Upload the artwork, set the size in millimetres or inches, and download an STL that has already been checked for printability.
How it works
- 1
Upload your artwork
SVG gives the cleanest edge because it is already vector data. PNG and JPG work too — the studio traces the outline for you, so a black silhouette on a white background gives the best result.

Set the size and the offsets
Type the width or height you want and everything scales to it. The outer offset is the cutting edge and the wall that carries it; the inner offset adds material inside the line, which is what stops thin shapes tearing the dough.

Tune each area separately
The Polygons tab lists every closed area the tracer found. Give a shape its own extrude height, drop an interior detail to an embossing depth, or leave a counter out of the cut entirely.

Check and download
The print-ready badge fails the model if it is not watertight, if a wall is thinner than a nozzle can lay down, or if it will not fit the bed you told it about. Then export STL or 3MF.
What makes a cutter print well
A cutter is a thin wall standing on its edge, so it fails in predictable ways: the wall is too thin to print, the blade is too sharp to survive being pressed into dough, or an interior detail is so narrow that the dough never releases.
The offsets exist to answer all three. Widening the outer offset thickens the wall without changing the shape you drew. The inner offset pulls material inward from the cut line, which is how a spindly letter or a thin tail becomes something that survives a hundred cookies.
- Wall thickness
- Around 0.8 mm — two passes of a 0.4 mm nozzle — is the usual floor. Below that the slicer starts skipping perimeters and the wall goes hollow in places.
- Cutting edge
- A tapered edge cuts cleanly and stays strong. A knife-thin one looks right on screen and chips the first time it meets a cold worktop.
- Height
- Most cutters land between 12 mm and 20 mm. Taller is easier to press by hand; shorter uses less filament and prints faster.
Printing and using the cutter
Print it flat on the bed, cutting edge upward. A 0.2 mm layer height, three or four perimeters and 15–20% infill suits almost everything here, and none of it needs supports when printed flat on the bed.
PLA is the easy choice and is fine for cutting dough that is going straight into the oven. PETG takes hot water better if you plan to wash the cutter often. Whatever you choose, print with a fresh nozzle: a worn one rounds the very tip, which is the part doing the work.
For food, treat a printed cutter the way you would a wooden one. Hand wash it, dry it, and do not leave it soaking or run it through a dishwasher, where the heat will warp PLA long before anything else goes wrong.
Where the free tier ends
Designing costs nothing and needs no account — you can upload, adjust and preview as long as you like. The first STL download is free as well.
After that, either buy the single design you need or take a subscription for unlimited downloads. Cutters stay on the free plan; the subscriptions exist for texture rollers, stamps, cutter sets and the parametric 3D objects.
Questions
What image works best for a cookie cutter?
A clean silhouette. High contrast, closed shapes, no gradients and no thin hairlines. SVG is ideal because the outline is already exact; with PNG or JPG the studio has to trace it, and a busy photograph traces into hundreds of jagged fragments.
Can I make the cutter emboss a pattern as well as cut?
Yes. Interior areas can be given their own height in the Polygons tab, so the outer line cuts while a face, a letter or a texture inside it presses a relief into the dough at a shallower depth.
What size should a cookie cutter be?
Between 50 mm and 90 mm across suits most biscuits. Below about 30 mm the details start closing up and the dough sticks; you can go smaller for polymer clay, where the material holds finer edges.
Do I need to know any 3D software?
No. Everything happens in the browser: you upload a 2D image and the studio builds the 3D geometry, so there is nothing to model and nothing to install.
