This is based off a puzzle my grandparents had when I was little. Spent numerous hours playing with the cube and making shapes. The main goal is to make a cube, but you can make it into anything your imagination can dream up. I recreated it using 1"x 1" x1" blocks in CAD and assembles the same way the original puzzle did. I used the Wham Bam smooth PEX build plate for consistant sides.
