FreeTextToCAD
One part. One export.
Describe a single printable part. Get a clean STL.
Free browser CAD for makers. Build hooks, brackets, washers, mounts, and enclosures with real millimeter dimensions, then send them straight to your slicer.
Built around one solid at a time. That focus is what keeps the models clean and printable.
What this tool is for
Exactly one solid part per generation. Name the part and give millimetre sizes. Detail is welcome — fully dimensioned descriptions work well here. What fails is scope, not length: a hinge, a lid, a sliding mechanism, or several objects will be refused however well the request is written.
Example prompt: A 30mm wall hook with a 4mm screw hole at the top and a 25mm arm
If that is not the ask, go somewhere else — or stop. A clean no is better than a confirm screen that never builds.

Built for printable parts
The best results come from specific, dimensioned prompts. Here are the kinds of parts people make every day:
- Wall hooks and hangers
- L-brackets and mounts
- Washers, spacers, and bushings
- Knobs, caps, and simple fixtures
- Electronics enclosures and trays
- Funnels, pipes, and duct adapters
Example prompt: A 30mm wall hook with a 4mm screw hole at the top and a 25mm arm

Two ways to make a model — choose the path that matches what you actually have: a dimensioned part, or feature-based CAD you sketch yourself.

Frequently asked questions
Is FreeTextToCAD free?
Yes. There is no account and nothing to install. Describe one part, generate a 3D model in your browser, and export STL or OBJ.
Do you make assemblies?
No. Generate one solid at a time, or try CAD Studio for early feature-based editing.
Can I paste a full specification or brief?
No. One or two sentences with millimetre sizes work. Long documents with headers and bullet lists usually stop at the confirm step. Distill to a single part first. See the prompt contract.
Can it make screws, gears, and other hardware shapes?
Yes, you can ask for bolts, knobs, gears, adapters, and similar parts. Printed threads and gears work best when they are a bit oversized, so include the size you need and test the fit.
Do I need to install software?
No. Everything runs in your web browser. The CAD engine loads once (about 60 MB) and then builds models locally on your device.
What kinds of parts work best?
One small printable part with clear dimensions: hooks, brackets, washers, knobs, mounts, enclosures, and trays. Full assemblies and pictorial shapes are out of scope.
Can it make a model of an animal, a face, a vase, or a logo?
Figurines, characters, animals, and decorative forms from text are not supported. To draw the shape yourself, use CAD Studio. Mechanical parts with dimensions use the Generator.
