When i first started this project in November, it was my goal to successfully reproduce each part. However, when it came time to scan and 3d print a prototype, the detail needed within the teeth is enormous. I contracted out to two companies who used High Resolution scanning and SLS printing (high res printing) to print out the nylon replicas. They proved too granular and rough to work with the other parts. I then asked the machinist on providing a negative for the gears. He said it would be expensive and that the end product might not be feasible. It's my goal to get all parts reproduced and i'l be dedicating more research to see how i can get these gears out. They are just too risky to offer in a Kickstarter project.
