Drela AG11 Airfoil Micro Drone Propeller (36.28g thrust @ 3V) by emanuelbucsa

I managed to design this drone propeller by using the Drela AG11 airfoil. Testing was performed on the Drone Propeller Thrust Tester (test results below).
I printed this part with a slow setting, with the help of a 0.2 extruder nozzle at 0.04mm layer height. I deburred and cleaned the print using a Precision Knife
After this, I went on and sanded it with a 400 grit sandpaper.
Here are the readings for a few voltage presets (also visible in the pictures taken):
1.5V => 13.19 grams
2V => 21.87 grams
2.5V => 30.34 grams
3V => 36.28 grams
The included files consist of all shots taken during the test, with 6 text files that have all the airfoil coordinates used in the build, the printable STL files and the SLDPRT files. Should you like to use the propeller, you should grab a bunch of 8520 coreless motors.
You should use the SLDPRT files, should you want to make your own changes to the drone propeller.
P.S. Airfoil plotted with the matplotlib library for python.
