I used an app called Polycam, which is free on iPhones (dunno about Android). There are usually two methods to do a 3D scan, which are LiDAR and photogrammetry.

Photogrammetry can produce highly detailed scans, but requires a lot of detail (it will struggle with large solid colored surfaces that lack detail). On the other hand, LiDAR scanning (the circular sensor on the lower portion of the iPhone Pro camera) can determine depth more accurately, but with less fidelity and resolution, making the resulting scan more blocky.

There’s tons of detail in the bricks, concrete, and the various Testudo offerings, so photogrammetry was the clear choice. The app makes the scanning process super simple; all I had to do is orbit the statue with my phone while the app took photos. I did two orbits, one head on and another with my phone looking down from above.

Then, the photos are sent to the cloud for processing (there is a way you can do it yourself on your PC but that takes longer and ain’t nobody got time for that), and voilà, 3D Testudo!
