Hi, I have been looking for a long time for a model of a trihedron that could be used as a tool for training or even for normal work on a coordinate measuring machine or other cnc machines. Unfortunately, I didn't find anything suitable, so I finally made my own model. I will be very happy if some of you also find it useful. It's made up of simple components for seamless printing, then you glue it together and that's it.

Good luck!
