A birdhouse that was created in several parts. 

The parts are all screwed together with an m5x0.8  12mm screw. The threads are pre-modeled.
You can find these in stores such as Amazon. You need 12 of them.

I printed it in durable PETG which makes it very sturdy. 

The floor is equipped with drainage areas.

The windows and door frames have a click mechanism that holds the parts securely. They are not screwed together.

Due to the multiple parts, you can choose any colors you like.
