For this project we were to construct a passive phone amplifier. Mine was made using relatively simple tools and shapes.
To start I added a hexagon to the work field
I then extruded it up a straight line, had the hexagon taper out at a 10 degree angle, and have the hexagon do a 180 degree turn going up the line
I then cut a rectangle that was 80mm by 15mm into the top, with two smaller rectangles cut below where the speakers of the phone are located.
I then extruded the rectangles below the speaker
Next I used an offset plane to sketch two hexagons that would cut into the object to act as speakers
I then filleted the edges to help cut down on print time
Finally I reduced the size of the speaker by using the push and pull command to make the speaker shorter.
The final product fits the iPhone 8 with an Otterbox phone case
