This is one of the two models that are stackable. 

A new parking lot with a garage entrance with enough space for 5 cars. The design is stackable and the best part is that the background can be with either a printed image or a custom 3D printed logo. There are a few examples on the documentation that you can print and glue!

This is the smaller version, the big one is also available here at MakerWorld, and it should be used as a base for a higher staking tower.

I intend to make more backgrounds and logos, just leave in the comments which you want to see and I'll try to make them!

If you want to make your own design, the background should be a 240x70 pixel square (not really a square) with an empty square on the bottom right side with the measures of 72x54.
