Export your scan under a 3D format, such as .stl or .obj, and show it off with publishing services such as sketchfab.com. If you want to use it to create a 3D-printed object, use Scanect or ...

Some readers may consider that a revolting oversimplification, but it is a helpful one to make a point about how 3D scanning, 3D printing, and CAD work do (and don’t) work together.

3D scanning in general is pretty far from being as simple as “point box, press button”, but there are tools available to make things easier.

With OpenScan project software, Raspberry Pi, and the Pi camera v2.1, Megel created a budget-friendly 3D-scanning system that's able to capture highly accurate 10-micron 3D scans with relative ease.

This app has a free mode if you want to get familiar with the scanning process, but you’ll need to subscribe if you want to export or share your 3D models. Finally, you’ll need something to scan.
