What you will find here
3D Hangar develops printable aircraft and model-rocket projects, from small gliders to larger RC structures. Our library brings together interactive CAD previews, exploded views, current file packages, build guides and equipment lists.
How we describe a project
A model’s CAD geometry, print preparation, physical fit, structural testing and flight testing are separate stages. We identify current limitations on the model pages and in the guides. These downloads are prototype designs; a rendering or an arranged plate does not prove an aircraft is ready to fly or a rocket is ready to launch.
Free files and useful feedback
All digital packages are free after name-and-email registration. Filament, hardware and electronics are separate. Download registration is not a marketing subscription. See our privacy page for how those details are stored and how to request removal.
For build questions, include the model, revision, part filename, material and a description of what you observed. Contact raderlabs@gmail.com.
Workshop journal
The blog explains project choices and assembly preparation using our current models. Articles are written under the 3D Hangar name and dated when published. Equipment brands describe components or compatibility; they do not imply an affiliation or endorsement.
