Japanese Style 7 Eleven Store Scale

I'm working on a Japanese Diorama for Hot Wheels in 1:64 scale. Its flat on top to make it simpler to print and I don't know a easy way to divide a building for parts then to reconstruct it afterwards . If you know please remix.

I have other designs that will complement this print.

Please adjust size to your needs.

This is my first building, so please let me know if you have any feedback or suggestions
