Jelbert Drone propeller for 180 size drones - 110mm length with 5mm shaft hole

thingiverse

This is my 3D printing drone propeller project tailored specifically for 180 size drones. The original props weighed in at 1.5g and measured 100mm long, yet were prone to breaking due to their thin, cheap plastic construction. I have taken a remix of another Thingiverse design (NACA4 Propeller Generator by Okatake), who generously provided the OpenSCAD script, and adapted it to meet my specific drone prop requirements. Please show your appreciation for this design if you find it useful and kindly upload any modifications you make. As this is an ongoing project, I encourage you to check back regularly for updates. To achieve optimal results, I made several adjustments to the original Okatake script, including resizing and modifying the hub. I also tweaked the roter_twist value from -25 to -20 to maintain a more aggressive blade angle at the propeller's outer edge. If you're struggling to attain sufficient lift, feel free to experiment with lower values (like -15) to increase the angle at the tips and boost lift. Through extensive experimentation, I have found that printing the props flat but vertically yields the best results, as seen in the included image. This approach ensures a smoother finish after printing, with minimal support material to remove. I initially tested the propellers using PLA, although I discovered that this material's brittleness makes it less than ideal for this application. Nevertheless, it does fly well and is affordable. I am currently experimenting with different filament types and will document any notable findings as they arise. Please use this design at your own risk.
