Yeti bottle handle

I needed a handle for my Yeti bottle (20 oz Rambler), but couldn't find one I liked, so I made one. I printed it in retina-scarring green Giantarm TPU; any softish (95A) TPU should work about the same. The handstrap attaches with screws; you'll need two M3x20mm screws, with a nut, lock washer, and two washers for each screw.
