This is a redesign of the PTC Lock Snap Repables http://repables.com/r/444/ . I really liked the original design of this clip, but the clip would not fit on this collect sold by Distech Automation http://www.dta-labs.com/products/bowden-coupler . So I redrew the design with a wider opening on the clip, and I also made the clip less thick. The clips holds the Collect up locking it in place. This takes the slack out of the Bowden tube for more precise retracts.
