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!

List of 3D printed parts needed:

• Case Top
• Case Bottom
• 4 Screws

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.

The two pieces snap together and the screws hold everything in place!
