Designs ready for 3D printing + editable Rhino files

I am developing a speculative design project and I need a designer experienced with 3D prototyping to help me.
I need 2 or 3 designs for 3D printing, preferably made with Rhino (and possibly -but not necessarily- the editable files).
I am building a very simple modular structure made of hexagonal pipes. I would need one file with the whole structure and one with the modular components of a single hexagon (or more, if required).
I will share screenshots of what I have managed to do with my limited knowledge of CAD Softwares to better explain the project. I need someone able to calculate the right angles etc. for the junctures to work, plus making it viable for 3D printing. Further details will be shared after the NDA signing. Budget is flexible, happy to pay more for fast and accurate work.
