Its a crane cabin to turn your A1 series into a fun little crane or something along those lines.
It prints flat and you fold everything in and use double sided tape to stick it on your unit.Let me know if you cant figure it out. You also need to use any sharp object to remove the brims that it has all around to prevent warping.
Also door is articulating with the thin brim-like structure if you fold it inside the housing.
I am curious about your opinion so let me know in the comments!
