Welcome to the i.materialize shop of Dr. Carl Hoff. I started publishing twisty puzzle designs back in January 2007 on TwistyPuzzles.com. Up until 2011, all my designs were made in POV-Ray which doesn't allow saving in a format suitable for 3D printing. However after seeing other designers offering 3D printed designs for sale, I've now taught myself some tricks and I'm offering my designs for sale here.
