It is just simple organizers for YLO Essential Oils that I have laying around. I made 2 versions with 4 slots.

the large one has diameter of 29mm for the slots

the small one has diameter of 23.5mm for the slots

I've found that the bottles has +/- 0.2mm variance so do please check your bottles first before printing.

I had no problem with the large bottles, but some of the small bottles are a bit harder sliding into the slots.
