@foone That's awesome! I'm wondering if you can avoid having to focus the camera if you rotate the floppy at the edge and center the camera on the edge?
I made a little cardboard model: 1. Floppy goes in, picture taken of back. 2. Rotate 90 degrees, picture of spine. 3. Rotate 90 degrees, picture of front. 4. Rotate a little more and dump the floppy.
The camera distance remains the same without distortion and gravity does the alignment. Hopefully. I have no idea how finicky this would be. 😅
