If you’ve been following my previous PLA Spring Motor Rolling Chassis designs (here: http://ift.tt/2jkNsEA, here: http://ift.tt/2jkSPE3, and here: http://ift.tt/1n0A68G), you will have noticed they are all “open frame”, primarily because I just like to watch gears in motion, secondary is of course weight reduction (or did I get that backwards?).
Dual Mode Windup Car is my first attempt at a “rolling body” design, but I did leave the windows down so I can still watch the gears. This design is a significant weight increase over the previous designs, and to compensate I did increase the final drive gear ratio from 1/25 to 1/16 to increase the torque.

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!
