For our second 3-D printing project we were assigned to take a simple object from our home and combine it with a 3-D printed object.

For my Hack’N’Toy project, I opted to create a designer encasing for a speaker. I found inspiration for the design of the speaker case online. The texture of the design is Voronoi. I discovered this texture online and thought it would look so cool with a speaker and lights inside of it.

My plan was to completely build the speaker from scratch and then place it inside of the case.

I purchased the speaker kit from Amazon, although I loved the clear case I took the measurement of the panel and designed it so that instead it would have the Voronoi pattern.

In order to apply a Voronoi Pattern in Tinkercad, you have to select the shape generator drop-down menu. Select featured then Voronoi. After, you can drop the filter onto the object that you would like the pattern to be on. Keep in mind that when you add the filter to an object it simply becomes a textured surface in order, you MUST then use the shape drop down menu to make this design into holes.

My design was quite simple it was literally the same shape as the clear encasement but with Voronoi instead.

The last obstacle I needed to complete would be to assemble the speaker.
To begin the I needed to attach the amplifier to the circuit board using a soldering iron

I then soldered the K2 to the front of the circuit board

Then I added 2 of the 10k resistors and soldered them at R2 and R4.

Next, I added capacitors. You must be careful with capacitors they are polarized meaning energy can only flow one way through them. If you compare the lengths of the legs of the one you’ll see that one is longer than the other. The long leg is the ‘positive’ side and the short leg is negative.

LED’s are polarized as well so they too must me soldered carefully into their positions, D1-D5

Place the 503 potentiometer into RP1 and the 103 potentiometer into RP2.

Solder the red wire to the positive connector of the speaker and the black wire to the negative

Solder the other ends of the red wire to the VO+ and the black to the Vo- on the board

Once you have completed all of these steps you will have this!

In all this project was a wonderful experience but unfortunately, my speakers did not produce any sound. After troubleshooting with my manager we discovered that I improperly installed the amplifier. On the amplifier there is a dot on top this tells you which leg is the first. So be aware of this simple mistake so you don’t make it your self. Also, another tip would be mindful of your Voronoi pattern. the “punch outs” are very difficult to remove. So you may not be able to remove them all without causing damage to your design.
