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.
