Prop Wrenches
thingiverse
If you fly mini quads, chances are high that you're going to be replacing a lot of propellers. The right hand tool for the job is these little hand wrenches, which excel at loosening and tightening prop nuts. The bigger one fits 1306 motors with CW and CCW spinners perfectly, while the smaller one handles 2204 size motors featuring nylon locking nuts. As I measured those with calipers when designing the wrench, it fits snugly - if anyone on the internet spots a mistake regarding M5 specs, they're more than welcome to set me straight.
