You might not be able to download a car yet, but a chair is a step in the right direction at least.
This chair is open source under creative commons and is free to download and reproduce for personal use. You still have to build it yourself (and it is kind of hard), but hey we can't do everything for you. Oh, wait, we can. You can buy it pre-cut and assembled from us. It is expensive, but the chairs are assembled by hand and finished in Norway from the finest Norwegian sitka spruce. And by buying it you support our work, coming up with more exciting designs.
