Hello,

I do not have any direct industry knowledge or experience regarding injection molding. I have a question regarding prototypes, probably 3d printed or cnc machined, but I am hoping someone on this forum can give me some advice please.

I was considering separating components from the device to be made at different manufacturers in order to keep the concept a secret. Do other designers/inventors do this, are there problems doing this when parts need to fit together such as interference fits?

Thanks, I know it's a bit of a dumb question.
