Animation of the triple-articulation of the cam.
My process of modeling the climbing cam involved taking a photo of the cam next to a ruler, and then importing that image into the CAD software (Autodesk Inventor). From there, I scaled the imagine based off of the 1cm increment on the ruler, and then traced each individual action component of the mechanism. For other components, I used a digital caliper to get necessary dimensions, and for complex models such as the handle, I could only eye-ball it using Inventor's freeform modelling tools to recreate it.
