VERSION 2
Tried to minimize overhangs for simper printing and less plastic.

VERSION 1:
Simple bait station for insecticide gel. Uses minimal plastic, quick and easy to print large numbers of the stations.

Nice way to put insecticide around the kitchen (or wherever) without getting it on anything or anyone accidently touching the poison. The tops fit snuggly. You may need to use superglue to hold the top on if kids are around. These really are not meant for keeping people or pets out, just convenience.

These three sizes were meant for Ants, German cockroaches, and maybe middle sized regular roaches. If you have those massive pet-sized cockroaches, you will probably need to make it bigger.

I do use glue sticks to hold things down. PLA probably wouldn't need it.
