Various printable containers that can be used to store things. This repository contains (sorry) some of the more useful ones.
Half size cases with lids. These were designed to fit into the latching 5-compartment storage boxes that Adafruit sells.
They were originally designed for M2.5 screws, but its entirely possible that they will fit other sizes within reason.
"Full size" cases designed for independent (out of case) use. These fit Trimcraft Aviation RC's screw bags, stacked together vertically.
A cylinder. Comes with a screw on top. Buyer beware. This was a test to see if I could make a better pill bottle for users with reduced strength in their hands (unsuccessful, for now; at least I think so).
A funnel. Used for transferring screws. Don't over think it like I did (it works for fluids with your slicer's vase mode though).
