Customizable Paint Can Replacement Lid

Customizable lid for a 1-gallon paint can (or customize for your own application). The center insert is optional and may provide a tighter seal if the original lid is removed. The version without the center insert can be placed over an existing lid, e.g. if the seal isn't so good on the original lid.

Recommend printing with a flexible filament such as TPU. Higher infill and higher end temperature may provide a better seal.
