I had this idea on the back burner for about a year while I was at college and didn't have access to my printers. I took a trip to the Bass Pro Shop Pyramid, and I saw these for about $5, and I knew I needed to pick them up and finally make it.

The carabiner goes into the ring that clips onto the cable
The loop goes onto the frame mount

Any sort of feedback is much much appreciated. If you would like design files ill be happy to provide them
