Insulin vial holder

I use my container to protect the clear glass bottle. It keeps it out of the direct sunlight, and a little cooler. Makes it easier for me when I travel. The A on the top is just to help me keep track of the bottles since I usually have another vial waiting. I used PLA and it is more than strong enough! The tolerances for a fit are tight. But if you have calibrated your printer should be just right. It fits a standard Novalog vial.
I am just having fun. If there is some change you would like ,
