PDF

This is my printable wrench to fasten M5 (8mm) and M6 (10mm) nuts, specifically Nylock nuts used for FPV props.

Small enough to be able to toss in your bag of FPV tools, yet effective enough to properly torque down your M5 or M6 nuts to fasten your propeller to the motor!

Recommended Materials

(Strongest first):
- PPS-CF
- PPA-CF 
- PA6-CF / PA12CF
- PET-CF

Below are filaments that you might want to print multiple, as they may eventually strip under heavy load:
- ASA
- PLA+ / PLA Pro
- PLA

Printing parameters

- 5 walls, 50% infill. Ultimately the part that interfaces with the nut will strip before you break the wings with your fingers.
