Insulin Bottle case

I made these little insulin cases to keep my bottles safe and organized in the cooler bag I use when I travel. The 10 ml (USA) bottles fit fairly tight, but a little filing of the internal ribs will loosen them up if desired. The threads will be a bit tight when they come off the printer but after a little use they end up perfect. I have printed several in different colors to help me track which bottle I am currently using. If you have AMS, it is easy to add stripes or other bits of color to make them even more unique. So far I have only printed in PLA, but I don't see why other filaments would not also work.
