Eye drop vial holder

My mother uses a variety of different eye drops, and over the years Cequa and Systane are two of the products she has used. She asked me for something that would hold the disposable vials vertically (I'm not exactly sure why), and after a few different prototypes I came up with this simple holder. She showed it to her ophthalmologist who was very excited about it, so I decided to post it here in case it could help other folks who use similar products. I could definitely have made it smaller to use less than the amount (only ~12g) of filament it currently takes, but it's much more stable this way, and has a nice tight fit. If someone has a specific need for one that's bigger or smaller, let me know in the comments and I'll try to post a modified version. I printed this in PLA with default 0.2mm print settings, but almost any material or print setting should work here, since it doesn't have any structural challenges.
