I am a Product designer engineer. I usually works with Solidworks, Sketchup and so on. I can made the drawings of every piece and the bill of materials needed. I am also a knitter so I can understand the machine and I know the normalized needles, the yarn used, and the materials needed (By the way, I think that crochet needles would be better for this project)
Please, contact me so we can speak of the project.
