XYZ-axis

This version can only be put together in one way. So you dont get your axis messed up!

This little thing is rather helpful when learning cnc axis.Though it might seem simple it is nice to have a real life subject in your hand whenever things start to get complicated.
I have talked to a lot of students who wish they had a thing like this back when they where taught the basics of a cnc machine.
Hope you all find it useful as well
