Six libraries, one search box

Printables

Prusa's library. Real prints — STL/3MF files, print settings, and photos of finished results. Filtered to free downloads only.

MakerWorld

Bambu Lab's library, and the fastest-growing one. Print profiles tuned per printer, and everything is free to download.

Thingiverse

The original, and still the deepest back catalogue. The only source that needs a key — a free app token takes about two minutes to create.

Sketchfab

A huge general 3D library, filtered to downloadable, freely-licensed models. Display meshes — expect to repair and scale them before slicing.

3D Warehouse

Trimble's SketchUp library. Everything is free, but it is architectural and product geometry rather than print files — watch wall thickness.

Community

Models uploaded here. The only source that declares whether a model is AI-generated, because we ask the person who uploads it.

Printables and Sketchfab are queried straight from your browser; MakerWorld, 3D Warehouse and Thingiverse go through the local server, because two send no CORS header and the third needs your token. Nothing is tracked, and Google's script is only loaded if sign-in is switched on. Always check a model's license before selling prints.

Is this model AI-generated?

Everyone answers this, and the answer is shown on the model. It is what makes the AI filter mean anything — no other library asks.
