Eye Drop Saver/Holder

This will allow you to save a single use eye drop vial after it has been opened for later use.
Option: You can add two 5/16" nuts to the underside to add some weight and increase stability. if you don't have 5/16" nuts, anything that will fit in a 6.5mmX14.2mmX12.6mm space with some glue could work. You can also add felt pads to make it more furniture/counter friendly.

Drop Holder 2 is smaller and doesn't use the 5/16" nuts for added weight.
