Are you looking for a way to protect your shiny new Circuit Playground? A 3D printed case can make it easy to keep your board safe and sound. You can mount the case to anything and embed it into other objects for quick projects.
This is a series of 3D printed cases designed to house a Circuit Playground, battery and switch. Three different shapes can be used for different applications. The board appears recessed allowing the NeoPixels to have a wider spread of light.
The Circuit Playground is exposed, allowing the buttons and sensors to be accessible for interaction and hooking up other components. A port opening allows a microUSB port for programming and powering.
Each case features a "locking" cover that snap fits shut when the nubs on the inner edges mate with indentations on the lip. Cutouts allow cables to plugin to the various connector ports.
If your new to electronics and the Adafruit Circuit Playground, I suggest you walk through the following guides to get the basics. The Adafruit Circuit Playground guide will walk you through setting it up.
3D Printing Services
Don't own a 3D Printer? Download the STL files and upload them to 3D Hubs to order the parts from a local maker and have them shipped to you. You can also search for local hacker/maker spaces for getting access to a 3D printer.
CURA Slice Settings
Here's a screenshot of the settings used to 3D print the top and bottom halves of the case. To get the most accurate tolerances for the snap fit features, you'll want to adjust your slice settings accordingly. The parts were tested with PLA filament, other materials that have more shrinkage such as ABS or Nylon may have different tolerances.
Parts and Supplies
You want to use machine screws (sized M3 x .45 x 5mm) to secure the Circuit Playground to the case. If you'd like to add a battery, you can make a slide switch adapter to easily power it on and off.
If you'd like to make changes or upgrades to the 3d model, you can download the fusion 360 archives in many different formats such as STEP, SAT, Solidworks, Sketchup and more!
