Just painted these modular walls from Printable Scenery.
They are made for the OpenLOCK system, and click into each other easily with clips. They are just as easily disassembled.
These are from Stone Walls set, and give you a huge variety of pieces to build whatever walls you’d like.If a rickety old fence is more your thing, then these ones, from the Ye Old Fence set might be something for you.
Excellent pieces, as always with Printable Scenery.
