UFO-Turbine engine

thingiverse

This radical engine, dubbed UFO due to its otherworldly design, revolves around an impeller that can reach mind-blowing speeds and deliver impressive power for small-scale applications. I engineered it initially to propel a tank, but I ended up constructing the tank too massive to accommodate this engine, so I'm gearing up to design an even more powerful version specifically for that purpose. To secure the back, you'll only need 5 M3 screws and nuts, along with an M4 long screw measuring at least 40mm to function as the shaft. The bearings feature a diameter of 13mm, a height of 5mm, and an inner diameter of 4mm. With careful assembly and some patience, this engine runs silky smooth and at breakneck speeds!
