This model was made to press corks into wine bottles by hand and or using a rubber mallet. It works for #8 corks but i have not tried it for #9 corks. 

I printed mine with a higher wall line count and an infill of 80% but feel free to try whatever settings work good for you. 

I recommend printing the handle on an angle like 45 degrees to distribute the force when pushing it or hitting it with a mallet. l was told that heating the corks in hot water before pressing them in makes it a little easier, this might make the cork slip out slightly because of the water on the cork but after the bottles sit for a while you should be able to push the cork down the rest of the way.

It worked for me great, give it a try and let me know how to make some improvements.
