Starter Outworld for Ants

I'm using the original small outworld made by dirkdirk for a couple of my colonies that still live in test tubes but need regular feeding. I disliked how easily the ants can escape when opening the lid to feed or remove leftovers so I remade the outworld from scratch.
I also made the connection hole a little more tight because I also had the hose slip out on some occasions.

You need a 2 mm glass or acrylic sheet in the size 50x110 mm.
A few cm of 14 mm OD aquarium hose, the hole of the outworld is a bit tight, you need to press it in hard.
A 16 mm test tube that you can now put onto the hose.


Note: because I remade the outworld from scratch the tabs to stack them on to of each other won't fit with the original version.
