Can a 3D Printed Propeller Launcher Outrange a Football Field?

Check out PCBWay here: https://www.pcbway.com. Thank you to ‪@PCBWay‬ for sponsoring this video by manufacturing and assembling the RPM sensor PCB! How far can a 3D printed, over-engineered propeller launcher throw? In this episode of MechaPrints, I push my human-powered launcher with a 182x gearbox to its limits against a Canadian football field (110 yards / 100 meters). The challenge: maximize how fast the propeller attached to the gearbox can be spun, measure propeller RPM with precision to optimize the design, and launch farther than ever before. This project combines mechanical engineering, electronics, and 3D printing: • Building a prototype RPM sensor and designing a custom PCB • Timelapse of 3D printing and assembly • Redesigning the output shaft for stability and sensor integration • Accuracy testing of the RPM sensor on a 5-inch propeller • Measuring the effect of gearbox lubrication on maximum RPM • Launches on the football field including the ultimate launch that reached 167 meters or 550 FT, far beyond the football field! 👉 Download the STL files & detailed instructions for the propeller launcher here: https://cults3d.com/en/3d-model/game/...
