Description
A tight coupler (tight to the axis, and tight in the rotation, but still allows a small angel error)
2xM4 screw
2xM4 hexnut
2xM4 screw
2xM4 hexnut
Instructions
The design allows shafts with different diameter to be mounted to each other easily.
The attached STL's is for a 10mm lead screw and a ~6mm stepper motor axis.
The force that the screw/nut gives seems to have fixed the axis perfectly. If it isn't enough it's an easy thing to improve the design with a "lockscrew" too.

After using them for a week or so I can tell they are working great and addressed the issue I had with a slight axis alignment error I had before and still beeing tight fit to axis aswell as the parts to each other :-)
