A no-assembly-needed earplug case from Printables will be more easily found in Mary’s purse than the previous small bag:
That’s the “grippy bits” version of the model, which really is easier to open than the straight-sided version.
I printed a few more, loaded them with earplugs, and put them where they may come in handy. In retrospect, I should have used clear PETG to show off the retina-burn plugs.
Living in the future is great!
