Racerstar Sprog motor wrench

thingiverse

Wrench for Racerstar Sprog motors - exactly what you need. These motors come with one major flaw in my opinion. They feature a smooth mating surface for propellers. During yesterday's flight, I experienced 2 loose props, so I created this wrench. To use it, simply slide it from side to side around one of the three arms on top of the motor and tighten the prop nut. I designed this specifically to work with my 2207, but it will also fit the 2205 and probably even the 2306 - a difference of 1 mm in diameter won't be an issue. As a bonus, you can use it as an emergency prop nut tool or to tighten/loosen M3 nylon nuts. If you encounter any problems with this design or its function, just let me know and I'll do my best to fix it.
