I did use some 3D printed details however these are not essential to finishing the project. While they add a bit of interest you could just as easily build this model and have an equally interesting diorama without the addition of those details.
I hope you enjoy watching and if you'd like to find the products and materials I used as the base for this diorama you'll find them at both Scene-A-Rama and Woodland Scenics, this link will take you to Scene-A-Rama:
