I wanted to make use of these little speakers I had lying around. The problem was, designing a box this small using wood would have been a pain.
Since I had a 3D printer, I decided to design and print my very own speaker box, custom for my purpose :)
I hope this Instructable will provide enough details on how to build one yourself! :)
Teachers! Did you use this instructable in your classroom?

Step 1: Designing the Speaker Box
This was my first project that I've designed myself using Fusion 360.
Here is the link to the model: https://www.thingiverse.com/thing:2795035
I measured the speakers and estimated tried to make the box as small as possible, taking all the electronics that will be inside into consideration.
NB: Please make sure you use the vernier caliper correctly when measuring. I made a mistake and was 3mm off on everything on my first attempt - good thing it wasn't that long to reprint.
Step 2: Tools and Components
- Soldering iron
- Light gauge wire
- Helping hands
- Hot glue gun
Step 3: 3D Printing the Box
I printed this using the following settings on my Anet A8:
- Layer Height: 0.32mm - since this print didn't have a lot of detail, I used a higher layer height to allow for shorter print time ~5 hours
- Filament: CCTree PLA 1.75mm
- Infill: 50%
- Print Temperature: 190/60
- Print Speed: 60mm/s
- Travel Speed: 120mm/s
Step 4: Fixing Mistakes and Reprinting
As I mentioned earlier, I originally measured incorrectly and thus my print came out 3mm smaller than intended.
Thus, I had issues trying to fit the speaker into the speaker hole.
You'll see in one of the photos above, I tried to use a rotary tool to make the hole larger, but failed miserably!
I then reprinted and stopped the print just after a few layers to test if the holes were correct.
I also realized I forgot to extrude the holes for the switch, jack and micro USB slot.

Step 5: Connect Components and Test
Before soldering, make sure you connect the wires via wire connectors and test everything is working
Step 6: Solder Components Together
Solder all the components together according to the provided schematic.
Step 7: Hot Glue Components Into Box
I used hot glue to stick all the components and they are fairly secure inside the box.
Step 8: Done!
I closed the box using the lid which snapped in perfectly - I didn't have to glue it shut.
The speaker isn't extremely loud, but can produce a fair amount of volume.
It was a fun project and incredible to see how you can go from idea, design and then producing a product in your hand. All made possible with 3D printing!
