Ant nest very basic

So I have thought about maybe getting a 3d printer, not just for ant stuff but also for that, so I have worked a bit in a program called autodesk inventor just to get familier with it in general, and I decided to try to make a nest in 3d file format just a very simple one, and here it is. # **Specification:** * Size: 150mm x 150 mm x 50 mm * The nest is 30mm deep. * Spongehole: 15mm wide x 30mm deep * Tube hole: 9.5 mm wide on the inside so that a 10mm tube would fit tight. * Screwholes: 2.5 mm in diamter, so that a m3 screw would keep a lid tight.
