Formicarium rooms and galleries maze style - Big size V.2

I made this maze style nest with a bigger size, because I have to move some of my ants to a new nest with a lot of space, because they are growing very fast.

I made a previous version (V1), but after print the first piece, I added some changes to improve the design (V2), like the possibility of fix the top part with the base using some screws.

From here you can download the just the V2.
