Cuburr - A Flexible Burr Puzzle

thingiverse

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.http://mysd300.blogspot.com/2011/07/flexible-burrcuburr.html 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 0.4mm thick.so it requires a printer capable of making thin flexible walls. Instructions The whole model is less than 1mm high, and works well with material 0.16 to 0.18mm thick. Probably not suitable for extruder-based machines with most materials. If you have a Solido SD300 or Invision LD, you can use the file cuburr_set2.sdm which already has all three pieces arranged on the table with peeling cuts. I recommend using the No Z-Fold option so for easy peeling. To solve it as a puzzle you'll need to bend, fold, and twist the pieces to get them together into the shape of a cube.
