About this 3D model

Why not Count down the 25 days of christmas with a big ol advent calender steam locomotive? The train consists of 4 train cars with doors numberd from 1 to 24, a coal tender for day 25, and a Steam engine. The pockets for each day are quite big to fit candy or any thing you wish. Best part: No glue or screws required! Everything is friction fit and snaps together!
