Collection of panels part 3

Hi all. I used to work in woodworking, but switched to 3D printing. I still have some files that I used.
Here's the first part:

Second part :

This is not my design and the author is unknown to me.
I provide the files as they are.

This can be used for teaching, designing or creating your own items.

I used some files in 3D printing when making souvenirs.
Be careful, the files are large.
