@MrInitialMan, The bigger issue will be the durability of the part, not whether it could be printed, and the availability of raw materials. But just know that NASA has recently test fired a rocket engine that uses some 3D printed parts, and that the automotive and aviation industries are heavily invested in research and development of 3D printed parts. Unfortunately for you and I, the machines needed to create those types of parts cost in the 100,000's of dollars.

With the abuse a sprocket takes I would not trust a 3D printed part just yet. Most of the current investment is in titanium (too expensive) and aluminum (too soft) for metal parts.

@JonnyHK, I just finished up a Fizik ICS / GoPro mount. I actually think that is better than my direct ICS / Fly6 mount as that particular mount really depends on saddle tilt. With the GoPro clip and Fly6 Adapter you can adjust the angle, to frame the top and bottom of the image much better regardless of saddle angle. I am going to take a break from all this modeling for a few days so I can finish Fallout 4.

One question, when I look at your clip it kind of reminds me of the fi´zi:k blin:k light, is that what it was modeled from?
