Pythagorean theorem exact measurements (pendant/keychain)

A Pythagorean theorem keychain or pendant. Created in Blender. I created the two legs, then created the hypotenuse by creating a face across the gap. I then solidified and subdivided the faces and extruded then individually in a checkerboard texture. Due to this process, the end product is exact by at least 99.9999%.

The checkerboard texture makes it easy to explain to children how the Pythagorean theorem works. Feel free to redistribute, but do not sell them. Enjoy!
