My friend downloaded the model from somewhere, I repaired it with [netfabb](http://www.netfabb.com/) (didn't like their software due to an annoying startup dialog and paid features), cut it with [slic3r](http://slic3r.org) (this program looked better) and gave him the [repetier](http://www.repetier.com/)-converted model back. + +![car without top part](/images/blinkiecar/wip.jpg) + +_This is how it looks on the inside._ + +Inside the car is a 3.3V coin cell battery, which is connected to two switches and orange blink LEDs on the bottom of the car.
