Hi, no problem to do, provided you give more detailed description (sketch, images of something similar). I have some experience related to pipe structures, worked on a project of Lego-like bicycles/tricycles made from standard pipes and custom made brackets.
I would make 3D design in Solid Works software and, after you satisfied with design can make production 2D drawings if needed.
I'm an electronic engineer with 5 years of experience in 3D modelling using SolidWorks. Good technical background.
