There are many parts to the Puzzle Cube, a lot of what the group was doing was experimenting with smaller dimentions so eventually the cube could be scaled to size.
Owen started off by designing 3d pieces that would be located in between two cubes that would be designed later. These pieces were designed on Sketch up and printed by the MakerBot. To make duplicates of these 3d pieces, Owen and I experimented and poured a cast into the mold that was made out of silicon. These pieces failed because they didn't fit together proberly and move how we wanted them to.
Another part to the puzzle was making 8 small cubes that were 1.25in; we cut these out of compressed wood. There were no problems with putting these together, everything was aligned correctly. The group was slowed down because the laser cutter did not cut through the wood the first time and it did take a long time to cut. These smaller cubes were used as an experiment to see if the mechinism would work, this part of the project failed.
A bigger cube that was designed was 4in cubed. Inside the cube were 3 intersecting planes that run along each axis with holes placed in them to allow marbles to pass through them. The holes were placed such that there are paths which the marble can take. In the end there are going to be 8 big cubs that can rotate around a center point.
