/Games/ChessPiece.foocad

A chess set, made mostly from "solids of revolution". (All except the knight, which is in the shape of a double G) Get the joke?

I've never printed it. The Knight needs to be taller.

Also, if I did print it, I'd make cylindical hollows in the bases to weight the pieces with coins.
