For this week’s project, we were faced with the task to create a speaker for our phones. We brainstormed with different variations of a powerless way to enhance the sound out of our phones, such as putting them in cups. However, we wanted to make them a little more interesting.
First, I made a trapezoid out of lines using the shortcut “L”. The top line is 120 mm, the two side lines are 40 mm and the bottom line is half the size of the top line, which is 60 mm.
Next, I extruded this shape upwards by 30 mm.
After that, I drew a rectangle on the top of the trapezoid using lines as well. This will be where my phone is going to sit. Considering the fact that my phone is 71 mm x 15 mm, I made the top and bottom lines 75 mm so I wouldn’t have to shove my phone in the slot to fit, and the two sides I made 17 mm for the same reason.
Next, I extruded the rectangle inwards 12 mm so it can hold my phone.
I then drew two squares on either side of the rectangle where my speakers would be located. Each square is 18 mm on each side.
Following this, I then extruded both sides deeper into the shape by 10 mm.
Then, I drew a square half the size of the rectangle on both sides of the object. Not pictures, is that to make this section of the piece easier, I changed the opacity of the object to 50%.
After that, I extruded the squares on both sides 1 mm. I did this so when I loft in the next step, there isn’t any overlapping.
Like I said, I lofted the outer rectangle profile to the inner square profile from the last step on both sides. These are the holes that the sound is going to come out of.
The next few steps are going to be the construction of the charger hole. For this part, I first drew a rectangle 10 mm x 5 mm in the center of the larger rectangle where my phone is going to sit.
Then, I extruded this rectangle down 17 mm.
After that, I made a two-point circle in the center of the bottom of the extruded rectangle I just made. Since the biggest part of the iPhone charging cord is 3 mm, I made the circle 5 mm for a little extra room so it wouldn’t be so snug.
Finally, I extruded that circle out far enough to cut through the wall of the device, I just did 25 mm, but less would suffice.
This is what it looked like in the end before I printed it:
