M4 nut holder/expander

thingiverse

I'm working on a car project, and there are some tiny M4 nuts behind the dashboard. It's so cramped that I have to loosen/tighten them with my fingers. I desgined this simple hexgon to hold an M4 nut and make it easier to spin them by hand. The fit is very tight. You'll need to press the nut in using pliers or similar. These were designed for Hillman nuts #127082 but they should fit similar hex nuts. Scale them up or down to fit other size nuts.
