When we first cut out all of our parts, we realized the parts were too loosely fit (so we needed to use glue and nails). I had to practice hammering because the wood was too weak for the nails and broke apart. Also, when we built our music reader, we had a little group conflict over the placement of the motor. We were split between whether to place the motor inside or outside of the wooden outer structure. In the end (without any ill feelings), we all decided to enlarge our base piece to include space for the motor. Since the original width was ideal for the photocells, we kept a middle separator in the box (wooden structure) to have that same sensor box on top (sensor box is where the photocells and the LED light are placed). Also, the first time we printed, the drawer was too low (the motherboard was not able to come out), and the sensor box had to be enlarged (because we forgot to consider the amount of space the wires take up). So, we cut out the pieces the second time with all of these changes and improvements.

We also worried about aesthetics, so we included musical note designs on our music box. We also used wood instead of Delrin because using wood gave the reader an old, classic feel.
We are still working on placing all the wires neatly inside the box. We will have to recalibrate our photocells because they will be in a different environment (before our sensor box was made of Legos versus wood).
