A friend of mine picked up a flexible plastic water bottle cage last time we
went to the bike shop here. Rigid enough to hold a bottle well but you can
squash them and they pop right back. It would probably work well on a uni if
it’s going to hit the ground often. I haven’t looked but they’re probably
available lots of places.
