Torque Wrench Calibration Tool

I designed this tool to calibrate the genial
"Torque Wrench Handles from 1.0Nm up to 3.0Nm"
There is such a tool showed on the fotos, but no file for it added.

It is designed for a 13mm hexgon nut, but I also added the STEP, so you can easily change it to your liking,
