As the nice original design, very simple to print: no supports or anything.

I don't need a pill box for 7-days, only need a shorter and smarter “memory cycle” of 2 days - meaning “this” and “next” day (attached a 3MF with debossed texts for that purpose): During the day can check, if the current day's chamber is empty (taken), and refill only the next day's chamber. Special chamber “1ST” is for 1st of month in case there is a 31st to 1st switch, otherwise the system won't work: 

• “1ST” chamber is refilled only, if next day is 1st of month
• “ODD” chamber is refilled for odd days, but not for 1st of month
• “EVEN” chamber is refilled for even days, but not for 1st of month

Respecting the license of the original creator and reapplying it.
