This week's selection is Thomas Davis' Liquid Pinewood Derby Car.
The ISDA (Industrial Design Society of America) and Inventables are sponsoring a Launch Day Challenge, where teams submit designs for 3D printed cars. And some of the designs are very far out, including our Design of the Week, the Liquid Pinewood Derby Car.
Inventables has a rather complete description of not only the car, but how it was created using ZBrush. You can even download the 3D model yourself - but we'd caution that 3D printing it could prove very challenging due to the confusing geometry of this unique model.
