This hinged clip replaces the standard bungy arrangement that Garrett provides. Instead of having to stretch the bungy cord over the handle, this device is designed to clip around the uppermost stem of the ATX. A clip can be then be used to attach the shoulder strap.Designed on Inventor, this bungy clip is designed to fit around the top most stem of the Garrett ATX. The thing can be printed as a whole on the 3D printer and carefully broken apart once compete. I printed with a 75% fill and full support. The hinge holes are sized for a 2mm rod. I used a rivet stem. The two sides are kept together by a bungly clip as illustrated in the photo.
