*UPDATE: Printed on 9/12 and it works! Took a little bit of cleaning up around the holes / caps, but everything fits. See updated pics Using some other designs I've seen, I designed my own formicarium. This one is smaller, measuring 130mm square, to better fit on my build plate. I've included a version with a lip at the top, which should accept a 125mm sq piece of glass. There are two large holes, which should accept 18mm test tubes One of them is inset quite a bit, so I plan on using that one for my water tube and leaving the tube embedded in the colony. The smaller hole is sized for the 7mm airline tubing I have on hand, to connect an outworld or another colony. I've also included plugs for the holes.
