Carabiner Clip for 21 mm shaft

I'm using this clip to attach my 21mm diameter gopro stick holder to a black diamond carabiner for quick deployment and neat storage while I'm moving.the exact design probably won't work for your specific carabiner and stick, as the dimensions are probably all over the place, but the principle is probably the same. I'll upload some photos in use when i have them. printing in ABS for flexibility, may need to taper the round part and thin it out for more durability.
