Hello:
My name is Gustavo Colin, I have more than 25 years of experience in industrial design using CAD software.
I can design and model the finger mobility support device and provide you with the 3D files in generic formats such as STEP, STL, IGES, OBJ and the drawing files with all annotations, tolerances and bill of materials in DWG, PDF, JPG format ready for manufacturing.
I can perform dynamic simulations and animations to check the correct functioning of the assemblies.
If I am awarded the project, I will need more information (photographic) related to the position of your hand during work, pressing a key, not pressing the key, position of your affected finger, etc.
You can see examples of work in my portfolio.
I will be happy to help you solve your problem.
Regards.
