M6 Nut Wing Wrench

I made this as a finger wrench / wing nut tool to help me remove/apply an M6 locking nut on a long threaded bolt. This little tool allows you to get enough torque with just your fingers for screwing a locking nut in places it might be hard to get a regular wrench, or where the threads are too deep for a traditional socket set. Just slide this "wing wrench" over your nut, and pull it back out when you've screwed your heart out.

The bottom features a perfect cavity for an M6 nut, and the top features a hole that an M6 bolt/thread fits through.

This is not a wing nut, because it doesn't have threads or a nut; but you could make it into a wing nut by gluing an M6 nut inside it.

I suggest using lots of perimeters and 100% infill (or 100% infill via perimeters) for the most strength. (See images of the 4 perimeters I used. Worked well.)
