The file 'Tello Quad Propeller 3D Printer Model' is (stl) file type, size is 191.7KB.
A remix of my tello propeller blades I made.
I haven't printed these myself yet, so print and use at your own risk, I would definitely recommend supports. Since the Tello is programmed to be used with 2 blade propellers, I'm not sure how this would affect the flight.
Let me know how it works!
Check out the youtube video of the design/print process of the original propellers:
