Scentbird Rotary Vial Holder
This is a spinning vial holder for Scentbird vials. When you rotate the base, each vial pops up one by one.
This design needs a 608 bearing in the base to spin properly. If you don't have any, you can print one here: https://www.thingiverse.com/thing:3506177/
I recommend putting some rubber or cork on the bottom so that it stays in place when you try to spin it
