Modular Fromicarium modules

Here I present my own designs for a modular formicarium: from test tube stand to the full grown colony. I do this project for myself, and update to which parts I use and require myself.

Parts marked ... require:
A_x - Acrillic glass panel of the thickness "x"
Mxy - an M screw of size "x" and length "y"

Test tubes used: 150(+-5) mm - length
15.0 mm - diameter
