I have a Revopoint Pop3 Digital Scanner, and my daughter needed this for a school project.

"Conch shells are conical and spiral-shaped, with a high spire and a noticeable siphonal canal. The shells are made of calcium and carbonate ions from seawater, and are so tough they can be used to strengthen cement...."

There, I had to learn that, so now you know too! : )

As you can see, this is free, but if you feel like paying me back, checkout out company FB page and like my work! Or, if you want something scanned, send me a message here on Thingiverse or on my FB page and I'm happy to help, ESPECALLY for a good cause (charities, educational models, STEM stuff for kids, etc.)
