Hex extension

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/7zxK7TtZOk3

I made this because I needed a longer screwdriver than I had, so instead of buying a new one I just made this extension.

WARNING: it's very thin and weak around both ends, but that's what I needed when I designed it.

Works okay, but could be a lot better for sure, so feel free to make it better in any way
