bathroom stoppers

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3732883.

Needed new stoppers in bathroom, tweaked this one for flexible tpu with Tinkercad for my drains.

new dimentions bath 40:40:18, sink 38:38:20.

Sink was a little tight, could probably go down to 37:37:19 but it's a good solid seal so I'm happy.
