Straw of Trouble

thingiverse

I wanted to make a Tesla valve but messed up and made a version that was a 2 way active valve. So now it's just a straw that is makes it hard to blow air through both ways. Since it is not used for high pressure short duration it isn't that noticeable when used. I would suggest using a food safe coating to stop the micro gaps between layers making small holes. I would suggest using food safe art resin if you want to use it as an actual straw.
