A spiral sea shell I captured via photogrammetry. This was only my third attempt at photogrammetry and came out well. 

I have not printed it though prusa slicer accepts it. When it asks you to convert units for meters to mm accept the change. If I were to print it I'd raise it up off the print bed and do organic supports. 

What I really wanted to do was contribute a public domain seashell others could use. Includes a .zip file with object and texture.
