About this 3D model
I have created 3 build trays: 1) 8x pawns 2) knight, bishop, rook (which you can probably add two to the build platform to print) 3) king, queen Each chess piece is split into two components: base, and piece. The tolerance between the two pieces is 0mm (transition fit) and should therefore fit tightly together without even the need for glue (although some can be added to keep them together if necessary).
