Here is a Monopoly piece I created where you can stack the houses to become a hotel as you go along.
The game piece is 20mm x 10mm x 10.428 mm tall.
Filament Brand: Other - ABS -
I used Cura to slice the model, I have included a text file along with a picture of my settings I used. You can get even better quality printing at 0.1mm layer height.
Here are my finished game pieces, I wanted to make sure they fit together before posting this.
