Stackable Storage Tray for Breast Milk Bags

We needed a storage system for our freezer chest full of Medela breast milk bags so I created this stackable tray.   The bags we use are approximately 105mm wide which is the most important measurement if you want your bags to fit perfectly out of the bottom slot. The length of our bags are approximately 175mm but that does not matter as much since the top of the bags are a bendable flap.  If you have different bag dimensions it would be easy to scale the x and y to fit your needs.  Each tray stacks about 10-12 bags.

No supports needed.  

I didn't care about looks, just speed and functionality.  I used PLA, 2 perimeters, and anywhere between .30 and .40 mm layer heights on a .6 mm nozzle.  

It's a tall and thin-walled model so I would print the perimeters slow so that the top of the walls print cleanly.
