I was doing some bike maintenance today and wanted to disassemble my rear hub. It turned out that I needed a 12mm Allen bit for that, which I don't have. So I 3D printed one! And it worked! Torques safely to 5Nm and I only needed 4Nm for the job. Haven't tested higher torques.

How do you really know it torqued to 5 Nm? Did you test this on a fixed nut?

I would like to see real yield curves before trusting the torque bales coming off a plastic socket.
