This is Stewart Coffin design #97. This puzzle is very difficult to make in wood, but simple for 3D printing. Print 3 copies of the basic piece, plus 3 mirror images.
The design of this puzzle begins with a standard Diagonal Burr, with pieces made from 6 cm x 2 cm x 2 cm sticks. The puzzle is then squashed by a factor 3/4 along an axis of 3-fold symmetry.
This version is quite small as printed and falls apart easily. It will be more stable if printed larger.
