This pawn is a step file, kindly shared by squar3d. His scan allowed me to modify the base. This is a work in progress, I will try and clean it up bit by bit.
EDIT: 2/26/18 - I uploaded a repaired/decimated version. It is reduced to 100k faces and was run through netfabb to make sure it is manifold. I then ran it through a second decimation in Meshlab trying to smooth it, but it came out all chewed up. I'll have to try it again with more faces.
