US standard tub stopper

A replacement stopper for drains in US standard bathtubs.  It is designed to provide a better seal than store bought options.  A generous knob on the top allows for easy removal.

Print in a flexible material like TPU.

Print with the top side toward your build plate to make sure bottom surface is as smooth as possible to provide the best seal.

This will print without supports, however, I do recommended them to prevent an excessively stringy surface.

Note: Yes, TPU can be printed with a Bowden tube.  Print at about half your normal speed and minimize or eliminate retraction.  I use an all metal hot end and Capricorn tubing on my Voxelab Aquila (Ender 3 clone).  I have been able to print at 30mm/s and 1mm retractions without issue (other than some stringing) using the cheapest TPU I could find on Amazon.
