28mm modular castle walls

In my third DnD project I decided I needed some walls to up my game in being a DM. So i designed a modular system, and after three iterations of connectors I landed on a simple small stick being the easiest assembly method. The walls are 10 cm high, (20 feet in 28mm scale) and occupy a 5x5 cm space (10x10 feet to scale)

I hope people enjoy this, please take some pictures if you use them, I'd love to see it!

If you have some suggestions for other pieces please leave a comment.
