Stackable Insulin Vial Organizer

My wife and son both have diabetes, and we needed a better way to store insulin vials without taking up half the fridge with bulky boxes. This stackable organizer holds 12 vials per tray, so you can store 12, 24, 36, or more by printing additional middle layers (the larger design). If you only need space for 12 vials, just print the base tray and cover. For 24 vials, print the base tray, one stackable tray, and the cover. The cover also helps block UV light, which can affect insulin quality.
