Welcome to the Shapeways 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 designs for sale here at Shapeways, I'm now learning some new 3D modeling software which will allow my designs to be printed.
