Cuburr combines a traditional three-piece-burr puzzle (the inner part) with a six-piece-burr puzzle (the surfaces) by connecting them with flexible hinges.

I designed this model to exploit the unique traits of my SD300, an LOM 3D printer. LOM, or Laminated Object Manufacturing, builds 3D objects by bonding thin sheets of material (paper or plastic) and cutting the contours into each layer one-at-a-time The walls are 0.2mm to 0.4m
