Ant Feeder with Granary module (Small, Medium, Large)

This is my approach for feeding my ant colonies. So far I was using small single trays for every type of food, but the cleaning and refill procedure was unnecessarily complicated.

Thus, I created these three sizes of Ant Feeders, where the Medium and Large one have an optional "Granary" Module für granivores like Messor barbarus. Now I just have to take one piece out, clean it, resupply it and put it back into the arena :)

Durability should be quite good, just make sure to use a bio-compatible, non-toxic filament (I'm using PLA).
