The file 'D6 Dice With Blank For Balance Tetris 3D Printer Model' is (stl) file type, size is 46.8KB.
@paulorfo offers a D6 die but I don't like how it includes both the S and Z Tetris pieces and not the L and J. Removed the line to distinguish between S and Z, and replaced one of them with a blank spot.
