Ant Farm with Outworld

thingiverse

I created this for my colony because I didn't like the parts from certain stores. The hole has a diameter of 15.4mm. Should you use larger or smaller test tubes, let me know and I will change the diameter. Behind the grid you place cotton and if you want some pieces of expanded clay. Would be happy if one or the other prints it and possibly suggests improvements. Have fun with the nest and the outworld.
