Designing & 3D Printing Some Cases for My New Circuit Boards for Audio Prototyping

Designing & 3D Printing Some Cases for My New Circuit Boards 

 The beginnings of a final design

In order to put the finishing touches on my custom designed circuit boards, I figured its about time to build some cases for them. The final addition was a set of 1.5", 4-Ohm speakers I just purchased to complete the project. As shown below, iteration v1 of a case was pretty rough, just figuring out and confirming the basic measurements and form of a design. This ended up being very bulky, which would be OK for use as a tabletop speaker or intercom etc.

In the case shown below, V2, I opted to make it longer instead of wider. I tend to like this layout a little more. There are still a few tweaks to make, like lowering the speaker down into the case, so the USB cable will plug into the MCU without being blocked. I may add round holes for the buttons, but I kind of like the square layout, I still need to wire up the speaker, but this is how it will look.

Once I make the necessary changes to this form, I will put the files in the associated GitHub repository here

I'm still trying to decide on a cover, whether or not I really need one, and if so, how to make it snap in and out, so it is easy to remove. I wish I would have made the PCB a little smaller, which I could probably do pretty easily by rearranging the components. All in all though, I think its pretty good for a first attempt at building a real circuit board with functional components. Thanks again to PCBWay.com for sponsoring the PCBs!
