Constant overhang angle keeps the horizontal plane steady without requiring any supports. A consistent 3-shell print thickness on the horizontal plane is guaranteed.

The original lip remix was not consistently wide on the horizontal plane, which necessitated extra infill that ran a higher risk of leaving gaps and added more print time. The updated version maintains a constant 3-shell thickness throughout for maximum stability. Thinner versions of this mask (2 shells) have been removed due to their increased safety risks. They are fragile and prone to many gaps. [UPDATED] 2020-05-03 After several requests, a lip has been added to the original v1 mask and uploaded. However, unlike the other v2 files here, the horizontal thickness of this lip is not constant. Since this v1 mask is significantly thicker than the v2 versions, maintaining a consistent horizontal thickness is less crucial but still possible upon high demand.
