Ratchet Wrench

This design was inspired by "Patent Remake: 1909 Ratchet Wrench" video on YouTube, where he found an expired patent from 1909 were the ratchet action of this wrench was very simple yet effective, and this model is 3d printable version of it, it has swappable head for different applications which ill add after i make sure it works, the torque was tested and with some debatable results it can withstand more than 6 Nm, but i have no valid way to test it accurately, it has some satisfying clicks that i found myself play with it at my desk.

you need:

4x hex screws m3 x 16.
4x m3 nuts.
