This is a modular pill bottle that lets you store different amounts/sizes of pills. I wanted something with a large enough diameter to store antacids, but small enough to comfortably fit in a backpack. Everything here is a right handed screw. I would recommend avoiding PLA Silk as it split very easily around the threads. ABS worked very well for me, but the support removal was a bit worse than PLA.

BOM:

Cap

Bottom

Tube (various quantities and sizes)

Assembly:

Remove the support material, especially around the threads. I used the back of a knife tip to really seat the groove. Screw everything together.

Things to try:

Left and right-handed threads on alternating pieces.

Labels for whatever drug is in the container.
