A pill organizer with 3/4/7 small cups, screwed into a holder that is mounted on the underside of a shelf/cupboard etc (with some double-sided adhesive), so it has it's fixed place without taking much usable space away.

A single lid for taking a cup with you is also available.

The 7-day version has (weekday) labels made in BambuSlicer, so you can edit them to your liking. There's a plate with single color and one with dual color i the 3mf.

The small cups are stackable for easy storage when empty. They also have a hexagonal profile for better grip. The cups are printed in vase mode and take only ~1.3g of filament each, so replacing them after some rounds of usage doesn't produce much waste.
