Hi there,
This is Bogdan from Romania.
I'm a mechanical engineer - specialized in the industrial robotic field, 3D designer and modeler (from time to time and some projects I could make the functional prototype too).
I'm doing product design, industrial design, reverse engineering, ideation, etc.
I have over 15 years experience working on various systems/devices across multiple industries, from concept to launch.
1 - i will need the dimensions/models of the T fittings you need to handle...
2 - by printing you mean on paper or 3d printing?... for 3d printing you will need 1:1 scale model as stl file, but will not be resistant enough (except maybe if you'll 3d print the disks in aluminum or stainless steel)
3 - there will be few more questions, but i'll ask upon connecting here...
hope you agree that the price will be different...
Regards
Bogdan
