Evolution of my other single pill pot, this one is slightly larger and has 4 sections with a rotating cover with window so you can empty a segment without the rest of your pills falling out. It's larger than the old pot at 55mm diameter and 23mm tall (the single pot is ~40mm in diameter but the same height)
The rotating inner part is held in place with an M3x12mm bolt which screws into the base (that's the shiny dot on the base you can see) it is made to take a bolt with a head of dimensions 5mm diameter and 3mm height. You could get away without the bolt, the design works perfectly fiine without it, but you will need to hold the inner in place if you tip the pot up to empty a segment.
I plan to add a 7 segment pot as well, as soon as I get the size I'm happy with I'll add the files
