Stackable test tube rack for founding ants

thingiverse

Stackable testing tube rack for founding ant queens. It is designed for five testing tubes with a diameter of 16mm and a lenght of 150mm. About 1cm of the tube is sticking out of the rack, which makes it easy to grab it and take it out. If your cotton wool plug is in further than that (which is recommended), the ants will still enjoy a dark founding chamber. The testing tubes sit in the rack slightly angled, so that even if the plug between the water chamber in the back of the tube and the founding chamber itself somehow starts leaking, the ants can save themselves to the very front of the testing tube and don't have to drown. This also means though, that there will be a little bit of water remaining in the bottom of the tube, which the ants cannot access. Just consider that when deciding about when it is time for the ants to move to another tube or even a proper arena. If you're wondering about the holes in the bottom of the rack: they're necessary, because to be maximum light proof, the tunnels for the tubes are fitting extremely precisely. This means that, if there were no holes, the tunnels would be air tight and it'd be a pain in the ass to insert or remove the tubes. I'm not going to redesign this to fit your testing tube size. Come on, it's not that hard, you can learn the necessary skills on YouTube in about half an hour, the software is free as well. Don't make me work because you're lazy.
