I’m 22, I live in wonderful city of Prague in Czech Republic. What I do is hard to define.
Oficially I’m a student on University of Economics in Prague. But what I do in my free time is much more interesting. I’m one of the core developers of RepRap project, where I design Open Source 3D printers. You can freely download and build my machine. My design is actually preferred worldwide by the community and build by thousands of builders. Generally Im trying to evangelize Open Hardware principles and of course 3D printing.
I teach on two czech universities.
I’m also writing a book about RepRap, called Getting Started with RepRap.
