Some years ago, friend of mine asked me if i can print some cold tea infuser that can be inserted directly into the pet bottle, as he saw something like it in China. Well there was none ready to be printed.
So after some thinkering, looking for suitable solution, food safe material and some try and errors here is a overview of something that should be a viable solution. I did not print this one my self yet, but previous unpublished versions were sort of working. Unfortunatelly without gaskets they were leaking. Hopefully no more!
I will add the printed result soon when I will get my hands on suitable gaskets.
The idea is based on strainer, that is inserted into bottle neck while covered by a cap. The cap is prolonged so it is also the cap for a bottle then the tea is infused. There is also a small tank, into which the strainer and cap can be moved once the tea is ready and you can cover the bottle with original cap, for example when you are hiking.
