Build a prop replica of the Memory Gun from the Gravity Falls TV show. Powered by the Feather PropMaker RP2040 and CircuitPython, this 3D printed prop lights up and plays blaster sound effects.
The 1.3in OLED screen displays a list of audio files stored on the Feather internal flash storage. Use the rotary encoder to cycle through the list of audio files. Press the button to trigger sound effects and light up the LED noodle.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Feather or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
