Thingiverse user SLI shared a great robotic track vehicle using servos and a rangefinder.
The Snow Cat utilizes a custom 182mm (Logitraxx) board that supports the Tamiya Vehicle Chassis kit mounting hardware that is widely available. It also uses the Tamiya 70168 twin motor gearbox. Unfortunately the Logitraxx board is not available yet, so if you want to duplicate this today, you’ll have to cut out your own chassis from a bare copper PCB. A 9×6″ bare copper PCB should be plenty big enough. You can mount your own electronics creation to that.

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!
