Human: **Note: This propeller fell short of reasonable expectations and may benefit from a re-print / re-test (if anyone is interested).**\r\nThis micro drone propeller was designed using the HAM-STD HS1-712 airfoil, which proved to be a robust choice. It was thoroughly tested on the Drone Propeller Thrust Testing Jig, with all results displayed below.\r\n\r\nThe part was printed at slow speed, utilizing a 0.2mm extruder nozzle and a layer height of 0.04 mm. After printing, it was meticulously cleaned using a Precision Knife.\r\n\r\nTo achieve the desired finish, I then sanded the propeller using 400 grit sandpaper.\r\n\r\nThe measurements for the four chosen voltage values are as follows (also see images):\r\n- **1.5V** resulted in **3.75 grams**\r\n- **2V** yielded **6.39 grams**\r\n- **2.5V** produced **14.11 grams**\r\n- **3V** produced **14.5 grams**\r\n\r\nThe included files contain all test images, as well as six text files with airfoil coordinates used in the build, printable STL files, and SLDPRT files for further modification.\r\n\r\nTo successfully operate this propeller, it is recommended to use a few 8520 coreless motors.\r\n\r\nThe SLDPRT files are also included, allowing you to adapt the propeller model to suit your specific needs.\r\n\r\n**P.S.** The airfoil was plotted using the matplotlib library for python.
