"Grabber" for backpacking water bottle

This is a small, lightweight 3D printed part that slides over the neck of an Igneous NOBO brand water bottle, for when you use a sports cap. (But I expect that it will fit other like bottles too.) These bottles are slick/slippery by nature, which makes them hard to grab, to pull out of your water bottle pocket. Especially if you're wearing sun gloves. This small part solves that problem. It gives you a way to grab the top of the bottle (gives “purchase”), to pull it out of your pocket easily. (The part will come in white.)
