CAD Designer Needed for CNC-Ready STEP Files (316L Stainless, Precision Wearable Parts)
Daniel was extremely helpful in sourcing suppliers at very competitive rates that I would not have been able to find myself. We also worked together on organising prototypes for my products and it has been going very well.
Will definitely work together again and highly recommend Daniel for any sourcing, prototyping or product management needs!
