Universal Lid

Universal lid designed for various tumblers and water bottles. Stemming from a prompt in Innovation Studio 1 about people losing their lids. Early prototype iterations used 3D printed PLA and TPU for a gasket that squeezed onto the bottle top. The design gained traction, prompting further independent iterations with overcast silicone. The current iteration features a blue silicone lid.
