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 Updates: The new wine aerator have a better venturi function and a bigger air ventilation hole to increse the flowrate of the wine coming out of the bottle.Model is made in Autocad 2014 After some trail and errors i finaly have a working aerator working as i want it to. I printed it with the top dripp free zoone down to the bed with support on 35° and 5mm brim I found this was the best way to get it as smooth as bossible and to stick enogh to the bed so it wont fall down.
