The base was designed to accommodate the project's electronics, but we also wanted it to look nice. Because of this, we chose to laser-cut it to take advantage of the aesthetic qualities of wood. This also made the project much more durable, which made it easy to transport.
The original plans for the box were created using MakerCase, but we adapted those designs to more closely serve the project's needs. Using AutoCAD, we cut out the shape of the completed puzzle on the top of the box, which would allow players to slide the pieces into place as they completed the puzzle. This served as a visual guide for the puzzle's shape. It was also super satisfying to slide the completed puzzle into place, which we felt was a good motivator/reward for playing the game.
We also lasercut a smaller surface to be placed inside the box. This surface facilitated the photoresistors, and served as a protective barrier between the blocks and the wiring.
On the back of the base, two small holes were cut for any wires that needed to exit the base. We only ended up using one (for the serial line, which connected the Arduino to an external laptop).
The top surface of the base, with the front and back surfaces shown below it. You can see the large bolt-shaped cutout on the top, as well as the two small holes cut out on the back surface.
The "sub-surface" designed to be placed inside the base. The small red circles indicate the positions of the five photoresistors, which are surrounded by an outline of the bolt. The eight circles outside the main cutout were used to hold the photoresistors in place.
