Here's how I printed this:https://www.youtube.com/watch?v=uZzoSL2_n_k&feature=youtu.be

I got really excited after seeing the trailer for the next Luigi's Mansion game for the Switch, so I decided to model the first stage shown in the trailer. Not bad for a day of work, I think.
Now that I played the game, I learned that this is actually Mario's hotel room.
I printed a really small version, which worked OK, but was quite hard to paint because of the walls. I uploaded an .stl with the walls separated so that you have the choice of printing as one solid body, or printing the walls separately.
If you try to print much larger than this size, then the overhang will start to bite you in the neck, so I'd try to keep it no larger than a few inches. If you really, really want to print this at a larger scale, please let me know and I'll provide you with individual assets so you can print them separately with supports, cut the supports, and glue them in.
