Zen Farming construction kit. Model comes with base sizes 6x6, 3x6, and 4x4. All tile models are included in the 3mf with blank tiles attached into files. Feel free to create custom tiles with the attached stl. For reference tiles are 29.9x29.9x5 with a cutaway in the bottom. Picture of this uploaded.

Special instructions: 

1. For the train and car assembly, insert the small triangle type pegs into the bottom of the train/car. I used glue to do this. For the bottom for the trains in the front and where the pin inserts I had to file a little bit to not catch on some of the train tracks. Picture of this attached.
2. Custom painting from slicer settings in height mode (I used 5mm from the bottom and zoomed in for some of the other objects)
