Hi Shapeways fans, Dumbbell Skewb are two Skewbs (Holey Skewbs, actually), connected by gears. The mechanism is similar to Dumbbell Cube, and it is also a challenge for intellectual weightlifters. Watch the Youtube video. Buy the puzzle at my Shapeways Shop. Read more at the Twisty Puzzles Forum. Check out the photo below and more photos here. Enjoy! Oskar
