This is a small and fast print for a Mini Bug House. I also designed a bigger object, the "Ladybug House" that you can find here on Printables.

This bug House can be hanged in your garden and needs to be filled with sticks, tree bark, dried leaves or pinecones. 

You can place a transparent sheet of plastic to observe the bugs and contain the material inside the little house. The lid closes the view and insulates the lower part of the bug house.
