Leonardo da Vinci ball bearings · 模型 258166
ball bearings are every where Leonardo da Vinci invented the ball bearing between the years 1498-1500. He designed it to lower the friction between two plates that would be in contact in his other famous design for the Helicopter. His helicopter would never have flown as humans to do not have anywhere near the power to weight ratio necessary to lift themselves against the force of gravity – this is the reason why birds have such large breasts their power to weight ratio far exceeds that of humans. Although the helicopter design went down like a lead balloon, the ball bearing is a different story. i have choosen FDM method of 3d printing method as it is economically cheap and easily available I'm from India, we did not have SLS printing commercially available so i opted for FDM method
