As I have organized all of my supplies with Gridfinity, I made this model to hold my multi-dose vials of Estrogen. I used a 1x3 bin with 0 height (generated through the SCAD Gridfinity) as well as the Insulin Holder model by Daniel Papukchiev (@dpapukchiev_785978).
This holds 4 typical multi-dose vials (~22.7mm diameter) and fits in a standard 1x3 Gridfinity space.
