FINAL PROTOTYPE

This design offers rotation into three different configurations and a snug fit, with a polished finish. It is designed to use the seal that came with the travel mug, which can be quickly slipped off of the original lid and onto the new one. The lid is water-tight when closed, and prevents splashes and spills while on the go.

Its major limitation is that you cannot turn the mug upside-down or severely jostle it without the lid coming off, but this is no different from the original black lid, as it is pressed on and sealed with a gasket instead of screwing on.
