Back in high school, I wrote SOČ (student-paper) about designing and building a small horizontal wind turbine (available here, only in Czech). It was an interesting experience and I learned a lot about aerodynamic. Ten years passed and I decided to revisit the idea of having a small DIY wind turbine. However, with a modern spin on it in the form of 3D printing the whole full-scale turbine on an SLA printer. Spoiler: it turned out perfectly!
