“Hopper” is a 3D printed hopping mechanism. Using two springs and a “mass” (the motor, motor holder, switch, battery, gears, axle and cams), the mechanism first compresses the springs then releases them to propel the mass upward to an abrupt stop causing Hopper to hop.

Modeled after windup and battery powered hopping toys from my much, much earlier years, Hopper was designed to demonstrate the difference between potential energy (energy stored in the springs via the battery, motor, motor holder, switch, gears, axle and cams) and kinetic energy (energy released from the springs and the resulting velocity of the battery, motor, motor holder, switch, gears, axle and cams), while entertaining the grandkids as well!

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!
