A simple rotating day selector to act as a reminder.
It could be useful for a variety of applications; tracking slow drying adhesives or paints, cleaning reminders, aquarium maintenance reminders, etc.
I printed both parts in PLA using the "0.2mm QUALITY" default in PrusaSlicer on my Prusa Mini. 0.2mm, 15% gyroid infill, no supports.
Depending how your print turns out you may need to quickly clean up the bump under the top part so that it smoothly rotates and falls into the notches on the base.
