We are going to collect pictures of 3d prints that have been done in different schools, too. The Czech school has started with a documentation of 3D printing in their school.
Here are some more objects from other schools.
This a video from the Latvian team about Latvian chess figures and 3D prints of chess figures.
There are much more 3d print objects in the picture gallery named 3D Prints (in materials -> images -> 3D Print).
