It's just a simple funnel that I thought up of in an afternoon. It's designed to fit inside the smallest standard pill bottles. The funnel is short and wide enough so that it doesn't move around alot when you place it on top of your pill bottle.
It takes about 40 minutes and 14 grams to print. Highly recommended to print it upright.
I couldn't make the outer surface come out perfect (as shown in one of the pictures). And of course this size could be too small for many other types of pill bottles, so any suggestions or future revisions are welcome!
