This is my adaptation of the single pill dispenser made by Brian Alldridge, with some improvements to suite my applications such as:

A threaded lid

a top pour funnel to allow easy transfer of small pills back into their prescription bottle

the ability for inserts to be used to fit a wider variety of pills

a curved "ramp" that guides a singular pill into the chamber.

NOTES: This is my first version and some tolerances are slightly off. The threads are a little sloppy, but a single wrap of electrical tape solved this. The bottom snap ring on the body portion is a bit too snug. I hit it with a demel briefly and it solved this issue. A revision will be posted addressing this issue.
