This is a remix, combining two elements...

ThinkerThing's Open Board Game. Grass Surface Brick - https://www.thingiverse.com/thing:739034

and "Monopoly house and hotel" using the hotel piece at https://www.thingiverse.com/thing:3169237

into what you see here.

Check out the single tile that started this all, here: https://www.thingiverse.com/thing:6292937.

As mentioned elsewhere, you may choose to sand down your tile bases to get them to fit inside the lip confines. They do make a satisfying POP/click sound when they do, and they won't go anywhere when snug in!
