The Wobbler
thingiverse
A few years back, a college professor owned an intriguing desk toy that has since been discontinued. Its unique design allowed the center of gravity to remain constant while it rolled. Inspired by this fascinating trinket, I thought it would be possible to create a 3D print replica. The model can be found at http://engy.us/misc/wobbler.stl, and a Python script used for its generation is available at http://engy.us/misc/wobbler.py. To see it in action, check out the video on YouTube at http://www.youtube.com/watch?v=5-jIQGCt1Bo.
With this file you will be able to print The Wobbler with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on The Wobbler.
