Minecraft Chess Set

Contains:
Wither (king), enderman (queen), skeleton (bishop), Ghast (knight), creeper (rook) and spider (pawn).
All pieces are ready to print straight after downloading. The circular base prints with it.
Yes the proportions are a little out, but that was so the pieces would not be wider than the base (~34mm).
