screw pill box day tracker

Original model designed in Tinkercad(!) (link). Designed to screw onto this pill case. It has 7 sides, each is marked with a letter for a day of the week (R for Thursday and a Sun icon for Sunday). Turn it 1/7th of a turn after taking your pill so you don't forget that you took the pills for the day. Also lets care-takers know if pills are done for the day.
