Description
At the top of M.C. Escher's famous "Waterfall" lithograph (https://www.mcescher.com/gallery/recognition-success/waterfall/) there is an interesting shape made of three intersecting cubes. I thought it looked pretty cool and decided to 3D print it.
It's got a nice heft to it (3½ ounces, 98 grams) and makes a great paperweight.
Pyrigan & Company

For the most part, I design and make high tolerance mechanical puzzles in aluminum, brass, and steel. You can read about them on my website (https://pyrigan.com). But I also enjoy solving other people's puzzles and when I find one that I think will come out reasonably well when 3D printed, I create an .STL file and try it out. If it's a success and the designer gives me permission, I'll add the puzzle here.
