There are lots of 3D objects on the web. Any file that is a .stl or .obj can be uploaded into Merge Miniverse, then easily loaded into the Object Viewer app (free) on a mobile device.
This is a unique find that was associated with a podcast episode I was listening to. The podcast is about a fossil with a story. The story talks about how the scientist used clues to solve a mystery. This particular story provided a downloadable 3D scan of the fossil they were talking about. Their intent was that their listeners could 3D print this and hold it in their hands. 3D printers are expensive and scarce, so I decided to try an AR experience with Merge Cube.
Listen to this podcast, and jot down things you find interesting.

Here are some objects that I have uploaded to MERGE Miniverse. The Castle and the Mystery Object were created in Tinkercad, and the other objects were downloaded from the web. Check them out!
