Formicarium (Ant Nest) (M size)

##### Version 2 with lots of improvements: http://www.thingiverse.com/thing:2131666
 

The design is inspired by the antscanada.com ant nests. Unfortunatly the shipping costs to my country are way to high, so i designed my own formicarium for my Camponotus herculeanus ants.
You can put some cotton in the base piece, stick the chamber on top of it and water the base piece from both sides (there are little holes in the walls), to regulate the humidity.

The entrance blocks are for 12/16mm aq
