Hi Cody:

Sorry to hear Sid is having a bad day.

This site has a sub (and sub-sub) forum related to 3d printed prosthesis:

http://3dprintboard.com/forumdisplay...-Robotic-Limbs

You might find something useful there or someone who can help.

I don't know exactly which tools are best for the sort of project you're thinking of. Importing mesh data seems to always be a kind of tedious process. Not sure what kind of scanner you'll be able to use for a "Sid Scan"..., though there are programs out there that facilitate extraction of mesh data from Dicom(aka MRI et al)files..., and I'm guess'n Sid won't sit still for a conventional 3d laser scan.

I don't know anything about Autodesk Inventor, but there might be better tools for dealing with organic shapes and mesh data, e.g., Blender.

Good luck!
