Hydro Flask Sock

cults3d

Print this Hydro Flask Sock with a flexible filament like TPU to slide over the bottom of an 18oz (532mL) bottle. Gives your bottle a nice grip on tabletops, avoids scratching surfaces, and quieter to set down your aluminum bottle. The inside diameter is slightly smaller than the bottle which makes it fit tight enough to not slide off. The bottom is open so it doesn't collect moisture in it. I think the PEI plate bed on the bottom creates a nice texture to prevent sticking to the table should moisture be a problem. It also assists when you have bottle tops that are difficult to twist-off by allowing a good grip on the bottom while twisting, and for those with arthritis. Update: I just added a Hydro Flask Sock for a 32oz sized bottle with a diameter of 90.6mm. I haven't tested it but it's a simple design and should work.
