Hi guys! I don't know if anyone is interested in some commission work for a total Rapid Prototyping Newbie? I am working on a pet project and need to create a prototype to see if my designs work. I uploaded the files to Shapeway and well. The cost was quite high because the parts are solid... So. I need some help with making them "hollow" and "watertight". You also need to balance stability and wall strength with keeping the cost down so material knowledge is a plus. You will sign an NDA before commencing work. Mess me with your rate and a breakdown of your experience.
