V2 16-Blade EDF Pod For 3-4S Brushless

thingiverse

V2 IS OUT! This version boasts improved aerodynamics inside the fan, resulting in a slight increase in thrust. It comes with an optional printable stand for testing purposes and features a fan that is identical to the previous version in terms of design, but with one key difference: the bolt holding it tightens further while rotating, rather than loosening as before. You can use a random M5-threaded fan mount or stick with the same adapter used with V1. --------------------------------------------------------- [V1] My first self-designed EDF unit for a brushless motor has been successfully tested today after being printed using PLA. It was paired with a 2800Kv motor, complete with a customized motor-to-fan shaft and a 3S LiPo battery. To my surprise, the fan performed flawlessly at maximum RPMs of over 30k, producing an impressive (and unmeasured) thrust of approximately 800g that is expected to increase with future updates. The fan boasts a simple yet effective design featuring 16 blades. I would appreciate any suggestions or expert advice from more seasoned designers! Although PLA may not be the ideal material for this application, it was my first week exploring the world of 3D printing and I wanted to test out everything. Despite its compact motor mounting design, it surprisingly fit snugly over an outrunner motor that I had on hand for testing purposes.
