potion bottle - with screw on cap

this is a simple vial/potion bottle with a screw on cap

it is about 15mm diameter x 100mm tall.

the file shared is clear PETG (blue) for the vial and with PLA for the screw cap, but it can easily be changed to PLA vial (see the red one in the picture)

you do have to carefully screw the cap the first time, as it cleans and fit the thread tightly, but after that, it works fine. 

it is water tight, but keep in mind that it is porous and might be hard to keep sanitary
