80mm Bathtub overflow cap with tabs

Most overflow drains on tubs are not properly water-sealed, so this is practical because if you are actively taking a bath, you may want to block that drain while you're in the tub. 

Best printed with TPU

Once again, do not pop this on, start filling the tub, and walk away, that would be an idiotic thing to do. This stopper is intended to be used when the user is in the tub to prevent/reduce the overflow drain from taking away from your bath.

DO NOT USE WITHOUT OBSERVING THE WATER FILL DIRECTLY.
