Our house has a lot of reusable drinkware, mostly Hydro Flask but others too. Many of them won't fit in our cupboard-space when upright so we put them on their side, but when we start stacking them they start collapsing all over the bloody place making a terrible racket.
It's a wall. For bottles. That's it. Tis about 8in tall and long and about 6in wide - enough to fit a general cupboard shelf and curved to fit a large/40oz Hydro Flask bottle perfectly. The reason for that is that you shouldn't need to permanently fasten this to the shelf; so long as there is a bottle shoved up against it, the weight will keep it in place and you can slide it back and forth along the shelf dependent on your bottle-storage needs. But you can totally permanently glue it down if that's your bag.
I included a “holed” version I made with the intent of saving plastic/weight, saves about 40% filament. However, it also added 8hrs of printing time with my settings so I opted to not bother. I didn't dial in my printer as well as I could have so mine looks a little ugly, YMMV. I also made the bottom-side edges curved a little so as to make it a little more sTyLiSh so be aware it's not completely flat on the bottom.
