Cartesian coordinate system

This is a coordinate system that I designed.
I use it for industrial robot programming and jogging but I am sure it can be handy for other applications as well.

There are two versions of the three axis, a one piece and a two piece version. When using the one piece version the rings for the rotations have to be inserted during the print.
The two piece version has to be glued afterwards.

Supports are only needed for the lower parts of the axis and the basis.
