Wine Aerator 2.0 for wine bottles

My own design of a wine aerator to insert into a wine bottle with non dripping top.

This is a work in progress and i would like to get some feedback from you so i can improve it.

The prototype i have printed is in ABS plastic 1.75mm
And the gasket is printed in Ninja Flex 1.75mm
The aerator fitts al wine bottles with an opening betwin Ø17-21mm

If you dont have Ninjaflex
Try with O-Rings as gasket or maby a rubber band will work if you cut and glue them as O-Rings
