Hello, everybody. I've been working on a product idea which lands itself very nicely with 3DP process. However I'm facing some engineering challenges. Does any one know of a site/service similar to 99designs bidding system only for professional 3D printed products modelers/engineers? Google does not seem to be helpful. Also, I'm curious if there were such a place - how useful would that be to this community? If you have 10 seconds, I'd appreciate you taking the attached poll. Thank you guys.
