EDIT 2020.01.31: I've created a more robust version of each centerpiece, addressing the weak points around screw holes in my previous design. I call this new version "Centerpiece_robust," with an added material thickness of 60% to reinforce those areas. Have fun exploring! EDIT 2019.04.20: I've successfully upscaled the 8.5 x 7.5 propeller by 130% and tested it on a Pylon Racer / Hotliner with 600 Watts. It worked incredibly well, proving its strength under high-power conditions. EDIT 2019.04.19: I've added spinners with both 2mm and 3mm mounting holes to the collection. EDIT 2019.04.06: Testing the 8.5-inch blades until they failed revealed an astonishing result: it took a whopping 1000 Watts and over 18,000 rpms to destroy them! However, please note that this test was conducted at room temperature with fresh PLA. Be aware that maximum load will significantly decrease over time, at different temperatures, or with other materials. Caution: This propeller is not designed for high-power motors, so use it carefully and test it thoroughly before using it in your airplane. At 12,000 rpms, the tip can reach speeds of over 500 km/h, which could cause serious injury if you get hit. I've tested the 8.5-inch blades up to 350 watts without any damage. There's also a more robust version of the 8-inch blades and center hub available in the files, designed for high-power applications. Print your propeller with 100% infill and 3-4 perimeters for optimal results.
