Sink Plug

Simple plug for kitchen sink.
The bottom of tapered section = 1 1/4" or 31.67mm.
The maximum diameter (top of tapered section) = 1 3/4" or 44.45mm

Made from flexible filament with 100% infill. It's a bit firm made this way, but it works in my sink. To make it a bit softer you may want to experiment with perhaps 4 perimeters or so with 20% infill (just estimating here as I did not try this myself).
