CAD Design for 3D Printed Frame

I'm in need of a skilled CAD designer to create a 3D model for a decorative 3D coordinate frame, similar to those seen in CAD software. The frame needs to be designed for 3D printing using plastic.

I've provided a similar concept in the photos. I would like to have the same size and concept with some of the shapes changed.
* The size of an individual axis should be 11cm.
* The final CAD design will have 4 pieces, the center and the 3 axes (see images attached).
* I would like to modify the central piece from a cube to be a 3D hexagon like the attached 3D hexagon.
* The 3 axes should then extend out from 3 of the squares on the 3D hexagon.
* The 3 axes should be square prisms rather than cylinders.
* The website "hubmachina.com" should be imprinted on the X and Y axis facing towards each other.

The output will be 4 .stp files and a render of the assembled model.

Ideal Skills and Experience:
- Proficiency in CAD software
- Experience with designing for 3D printing
- Understanding of structural integrity for decorative pieces
- Ability to create a modern, minimalistic design
- Experience with designing plastic components
