# O’Beirne’s cube

A six pieces interesting puzzle invented by T:H:O’Beirne. This cube was constructed with 24 rectangular block. Each block dimension is 3x4x6 unit. With the assembly of cube parts an 12x12x12 cube will be obtained. Here I will not explain this cube. But I can advise strongly reading this article about this cube. This puzzle described as a genius idea. Because you can obtain five different block in a cycle like a magic trick.

Puzzle parts are here.

I made this puzzle by using 15x 20 mm ready stock. I cut:

Red pieces:
3a x 4a x 12a
15 x 20 x 60 mm you must cut 6 pieces.

Yellow pieces:
3a x 4a x 6a
15 x 20 x 30 mm you must cut 12 pieces.

If you use this dimensions you will obtain a 60 x 60 x 60 mm cube. This is 12a x 12 a x 12a. I made a saw trace to the middle of red pieces. In this case the puzzle looks like made from rectangular blocks. For a better looking puzzle you can make chamfer to the edge of puzzle pieces before gluing them. After you can glue them according to the picture.
