4x4.5 Propeller

thingiverse

As I continue to push the limits of my FPV racing quads, I've decided to take on a new challenge: designing and printing smaller propellers that can keep up with their high-performance demands. The result is now available for your use, and so far, it has proven to be a game-changer on my trusty Diatone Tyrant 180. With the right adjustments to your printer settings, I'm confident that these props will come off the print bed without requiring any additional balancing or sanding. To achieve this, I recommend printing with a large layer height and slow print speed - a setting of 0.3mm and 20-30mm/s has yielded excellent results for me. In terms of infill, while 100% is always the best option, I've found that even a 20% fill rate works well. Additionally, maintaining high nozzle and bed temperatures will result in stronger props, as I've discovered through my extensive testing with PLA. Although I've only experimented with PLA so far, I'm confident that these designs would translate just as well to ABS or other materials. If you're like me and tend to break a lot of props, 3D printing new ones is an affordable and quick way to get your quad back in the air. Keep in mind that these propellers aren't meant to outperform those made from molds - rather, they offer a cost-effective alternative for enthusiasts who need a reliable solution. Print Settings: * Rafts: Doesn't Matter * Supports: Doesn't Matter * Resolution: 0.3mm * Infill: 20-100% * Notes: For optimal results, keep layer height large and print speed low.
