I have prescription eye drops. The meds are one drop per eye twice a day. The "individual" dropper portions are roughly 5-6 drops. They can be used and refrigerated for up to 24 hours and then finished off.... so.. good to have a place to keep them in rather than use a bag or whatever.

I suggest "finishing" the print if you make one to seal it so it doesn't build up bacteria or mold in the tiny layer lines.
