To make the pitch pipe more readable we will make a case with letters A-G that will line up with the 7 NeoPixels we're using. The case will be 2 halves that snap-fit together and 4 screws that will hold the Circuit Playground in place. No need to order specific screws and wait 3 days for them in the mail, they are 3D printed!

If you don't have access to a 3D printer there is more than likely a maker space or fab lab near you with more 3D printers than they can handle. You can pay a small fee at these places to have them 3D print your files right in front of you! These places also have equipment like laser cutters, a wood shop, and all the maker needs you could ever desire.

Check to see if there's a Fab Lab near you here.

If not, there are several companies that will 3D print your parts and mail them to you. Find a good one here.

Here's what all the parts look like after being printed, along with the Circuit Playground Express for reference.
