A customizable vial holder. I needed something that would hold various fragrance decants, but I suppose you could use it for something like ...science?

Defaults to a 3x3 grid. Square will auto-size for the number of vials you want to hold. Number of vials must be a number that results in a whole number square root.

Defaults to 14.5mm vial size with 2.5mm spacing between vials.
