Hello,
I am interested in your project and am confident that I can do it exactly the way you want.
Since I am a Senior Industrial Designer and have a lot of experiences working for a variety of products.
Please see my portfolio.
I saw the image that you need it in a 3D file. I will make a 3D model from it with Rhino first and get STL format.
Hope to hear back from you soon!
Best,
Kamran
