Build a sketch drawing toy using CircuitPython and 3D Printing! Use the Feather M4 and 2.4in TFT FeatherWing to make a portable sketch drawing hand held device.
Use knobs to move the cursor and flip the toggle switch to pen up or down and use the button to clear the display. This uses Display IO in CircuitPython to draw pixels on the TFT display.

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 Arduino 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!
