Spice Up Your Bench With 3D Printed Dancing Springs

Spice Up Your Bench With 3D Printed Dancing Springs

Not all projects are made equal. Some are designed to solve a problem while others are just for fun. Entering the ranks of the most useless machines is a project by [Vladimir Mariano] who created the 3D Printed Dancing Springs. It is a step up from 3D printing a custom slinky and will make a fine edition to any maker bench. The project uses 3D printed coils made of transparent material that is mounted atop geared platforms and attached to a fixed frame. The gears are driven by a servo motor. The motor rotates the gears and the result is a distortion in the spring. This distortion is what the dancing is all about. To add to the effect, [Vladimir Mariano] uses RGB LEDs controlled by an ATmega32u4. You can’t dance without music. So [Vladimir] added a MEMs microphone to pick up noise levels which are used to control the servo and lights. The code, STL files and build instructi...
