FunCap

This object is for people who don't want to have fun and struggling alcoholics. Print this part only if you have no reason to be fun.

Directions:
1) Print part.
2) Insert part into bottle for no fun mode.
3) Pull part out of bottle.
4) Have fun like an adult.

But for real though, if someone pulls the FunCap out of your liquor bottle and you can't find it, and you're trying to make drinks like a responsible person (i.e. 32% liquor 68% mixer), then print yourself one of these.

Drink responsibly with a FunCap.
Not for anyone under 21.
