How is the seal at the reservoir towers? My Truncorum are so tiny I'd be concerned with drownings in the new design.
I'm lightly sanding the tops to make them a bit more level, in response to some things I saw with the earlier versions.
I could incorporate small O-rings as a gasket around the reservoir, but that may be tricky to do since I don't want to apply too much pressure to the lid with the screws.
The only ants I've observed that could crawl into the reservoir were Brachymyrmex, and that was before I started sanding them down a bit.
