Vehicle
Push-toy cars, vans, jeeps and buses at any scale, with rolling wheels on rod axles. Any vehicle tows any trailer.
From 3D idea to laser-cut parts that actually fit.
laserpuzzle turns 3D models and a few parameters into flat parts for your laser cutter, ready to cut and assemble: toy cars, diggers and loaders that move, stacked sculptures, sliceforms. Kerf, clearances and a 3D collision check are built in.

How it works
-
1Pick and tune
Choose a generator, upload an STL or start from a sample, set your material thickness. The 3D preview updates as you type.
-
2Download and cut
SVG and DXF sheets with cut and engrave lines in separate colours and layers, kerf already applied. Works with any laser software.
-
3Assemble
Tabs, slots and press-fit holes are sized for your machine, and every part is labelled. Assembly notes and a parts list come with it.
See it move before you cut
The 3D preview is the finished model, built from the exact parts you will cut. Turn it, look through it, and put every moving joint through its paces.
Pose it
A slider for every joint (steering, lift, tilt); linked parts follow, as on the real thing. Play sweeps each joint through its whole range.
Range of motion
Ghosts of the moving parts across a joint's range show at a glance how far it goes and what it passes.
Checked while moving
Parts are checked for overlaps across every joint's range, not only at rest. If something clashes, one click shows the pose where it happens.
View cube
Click a face, edge or corner of the cube to look from there. Switch to orthographic for true side, front and top views.
X-ray
See through the plywood: pins, axles and hidden joints show up inside the model.
Explode and identify
Pull the assembly apart to see how it goes together, and click any part to see which one it is.
Generators
Each generator is a small program that designs a whole family of objects. More are on the way.
Stacked layers
Slice any STL into layers that stack into a solid shape, aligned by a spine or a dowel.
Sliceform
Two sets of interlocking cross-sections that slot together into a lightweight lattice of your model.
Excavator
A tracked digger with a turning house and a boom, stick and bucket on pins, checked for collisions through its whole range of motion.
Wheel loader
An articulated loader that steers by bending in the middle, with lift arms and a lever linkage that tips the bucket. Rolls on laminated wheels.
Fit test
A slot comb and a strip of rod holes. Cut it once per material to find the clearance your laser needs, before cutting a whole project.
Why laserpuzzle
Your files stay with you
Everything runs in your browser. Models are never uploaded; there is no server that sees them.
Nothing to install
Open the page and go. After the first visit it starts from your browser's cache, and it runs on Windows, macOS and Linux.
Fits that work
Nominal outlines, kerf compensation at export, clearance on every joint, and a 3D check that no two parts overlap, at rest and while they move.
Any laser
Millimetre-accurate SVG and DXF, cut in red, engrave in blue (your choice of colours), nested onto sheets of your size.

Questions
Do I need an account?
No. Open the app and start. Accounts will only be needed for Pro.
Are my models uploaded anywhere?
No. The whole engine (Python, compiled to WebAssembly) runs in your browser tab. Files you choose are read locally and never sent to us. We only keep anonymous, cookie-free visit statistics.
Why does the app take a while to start the first time?
It downloads its engine (about 22 MB) once; your browser caches it. On a decent connection this page starts that download in the background while you read.
Which lasers and materials work?
Any laser cutter whose software reads SVG or DXF. Set your material thickness and kerf, and cut the fit test first to find the right clearance for your machine and material.
Can I sell what I make?
Yes, things made with the free generators are yours. If you sell toys, you are responsible for meeting the toy-safety rules where you sell them.
Is it open source?
The core engine and standard generators are open source (GPL-3.0): github.com/fikander/laserpuzzle. See licences for everything the site uses.
