How many times have you opened a lunchbox and seen the same boring sandwich? Now imagine that same sandwich shaped like a bear, a star, or your business logo. Suddenly, mealtime stops being a struggle and becomes the favorite moment of the day.
The KingsCutter Sandwich Cutter is a custom cutter for sandwiches, cookies and dough. Upload an image, choose the design, and within seconds you have a print-ready STL. Then you cut bread, cookies, fondant or fruit into that unique shape only you can create.
What is a Sandwich Cutter?
It is a cutter with tall walls and rounded edges, designed to go through sandwich bread, cookie dough or fondant sheets without deforming them. Unlike a traditional cookie cutter, it is built for larger pieces and thicker foods, like a full sandwich with its filling.
With KingsCutter you customize it from any image: your kid's drawing, your brand logo, a letter, a cute animal. The AI detects the edges and generates the 3D model ready to download.
Why do fun shapes work?
It is not magic, it is psychology. Kids (and many adults) eat with their eyes first. A heart-shaped or dinosaur-shaped sandwich invites you to try it, turning a meal that often creates resistance into something desired.
- Picky eaters: a fun shape changes the relationship with food. That cheese sandwich nobody wanted becomes the star of the lunchbox.
- Lunchboxes and bento boxes: Japanese bento culture has proven for decades that food with shapes is happier and healthier, because it invites more variety.
- Parties and events: star- or number-shaped sandwiches for birthdays, pumpkin-shaped mini sandwiches for Halloween.
- Business: cafés and bakeries use exclusive shapes to stand out at the counter and on social media.
Sandwich cookies: the sweet trend
Sandwich cookies âtwo cookies joined by a fillingâ are one of the strongest baking trends today. The classic Oreo is over a century old, but today the artisanal, customized version is everywhere.
With a Sandwich Cutter you can bake two identical cookies in any shape and join them with ganache, buttercream, dulce de leche or jam. The result is a dessert that looks professional and tastes homemade. In Brazil, the brigadeiro sandwich is a classic; in Europe, macarons; in the US, whoopie pies. The foundation of all of them: two perfectly equal pieces, and for that you need a consistent cutter.

Ideas to make the most of it
- School lunchboxes: prep the whole week with shapes that rotate every day.
- Kids' parties: sandwiches shaped like favorite characters, age numbers or name letters.
- Valentine's Day: hearts for a surprise breakfast or sandwich cookies with pink filling.
- Christmas: stars, trees and snowflakes for December tables.
- Your own brand: if you sell coffee or baked goods, a sandwich or cookie with your logo is edible marketing.
Tips for a perfect cut
- Slightly cold bread: very fresh sandwich bread falls apart; refrigerate it for 5 minutes and it cuts clean.
- Firm, even pressure: press the cutter vertically without moving it, so the edges stay defined.
- Cold cookie dough: for sandwich cookies, chill the dough before cutting and you will see the difference.
- Quick cleaning: food-safe PETG washes with warm water and soap, and handles daily use.

Does the Sandwich Cutter cut the bread with filling, or just the slice?
It cuts the whole sandwich, bread and filling included, as long as the filling is not too thick or runny: the wetter the filling, the more likely the wall is to drag the crumb. Press straight down with the palm of your hand without twisting the piece, then lift it vertically.
The tall wall exists for one practical reason: to go through an assembled sandwich in a single pass, instead of cutting the 2 slices separately and lining them up afterwards. For clean corners, wipe the inner wall between cuts with a damp hand and chill the bread for a few minutes before cutting.

En la prĂĄctica
Based on our own measurement in the workshop, the system scales the whole outline when you change size: the same drawing cut at 7 cm and at 20 cm keeps the silhouette in proportion. That means one file serves both party mini sandwiches and the full slice, with no redesign required.
