Historically walls such as this were used to defend key areas that were deemed important to the ruling body.
This Castle wall pack will allow you to reconstruct defences that were typical of Feudal Japan and help reenact the long ago battles of the period whilst at the same time making a nice centre piece for your wargaming table.
The download zipped folder contains both STL and OBJ variants of the castle walls and has support sprues where required to help you get the best results when it comes to 3D printing.
