My first iteration worked, but in order to produce and ship, it needed a redesign. I have a 3D CAD designer that does all of my work. We brainstorm different iterations and he designs them in SolidWorks. We went back to Xometry for several more prototypes until we finally settled on our tenth design change; one that accommodated functionality, manufacturing, and shipping.
After speaking with many other product developers, we found out that it is very common to discover a mistake after getting a product manufactured. Having a place to reliably print my product was a huge help in that respect. The ability to make a change, print it out, and physically hold each design without expensive mold costs was absolutely priceless. I would urge anyone with an idea to spend a little time and money to get a prototype printed so you can physically evaluate the product in real life.”
