First Design Iteration
We chose to do a speaker because it is fun, functional and three dimensional. The design is simple and doesn’t take up much space. The main box is three dimensional with a hollow slit at the top that can fit an iPhone 7. There is a hollow cylinder that goes through the box length wise so the iPhone can project sound through the cylinder tunnel. We got ideas through Thingiverse from different iPhone speaker stands. Ours has a bigger platform base, compared to the iPhone speaker with a small standing base. We also saw some designs with an old-fashioned like spiral tunnel like that would be on a record player. We chose to not do that and instead have two holes on the both sides of the platform for sound to come out of.
We used a “regular box” and used two “cylinders” for the holes of it. The hole on top is a cylinder that we stretched out to form the stand for the phone. We then used the align feature to make sure it was center on the box. After that, we grouped the box and the cylinder and created the whole. For the wholes on the side, we used one long cylinder going into the box and aligned and grouped it too. Printability wise, there should be no difficulties because of the simplicity of the design and there is no support needed.

First Draft Print
Our first draft of the iPhone speaker turned out well. Before we printed it, we adjusted our original design to make the iPhone slit a few milimeters larger to ensure that the phone will fit. The phone stands up and balancs well. The speaker quality could improve. The aesthetics of the speaker could be improved as well. We also learned that the simple shapes helped make the print go by smooth.
Iterating the Design
We made a lot of changes to our original design. First, aesthetic wise, we added a JMU logo to the front and stars on the back to make it look more visually appealing. Next, we added cones to the sides where a circle hole was, this is to help amplify sound. We made sure the cones at touching on the inside and put different size holes in and made the side symmetrical for the speaker so that the weight would be evenly distributed. Lastly we added a pyramid type structure/ kickstand to aid with balancing.

Final Print
For our final print, we decided to add “horns” and expand the circles to come out of the body of the box to help amplify the sound. Our original design lacked the ability to do so. Also, we took off the kick stands on our print before this because we didn’t need the extra weight on the speaker we intended to need. Additionally, our first print with this new design- the speaker in the gray. We printed this on the Lulzbot Mini. However, this print ended up having many holes in horn part of the speaker. So, we ended up re-printing it (the blue speaker) on the Ultimaker. And it ended up coming out great. However, it had a lot of support that we needed to take out of it and it took a very long time to do so. We are very happy with our final project and hope other people decided to print this in the future!!!
