Bathtub Overflow Stopper

I wanted to be able to fill my bathtub all the way up so I designed this bathtub overflow stopper.

The mount (blue piece) is printed in PLA, the actual stopper is printed in semiflex. I uploaded the cura profiles that I used to print each piece. Semiflex is the perfect material for a drain stopper, it is flexible enough to squeeze into the drain but is still durable.

The brand of faucet and overflow drain on my tub is Kohler. Feel free to remix this design for your application!
