The following openlock 2x2 inch pieces are provided. First, straight shrubbery with grass on openlock bases or with 3mm thick bases which I call top caps. Then a second set of openlock or top caps that have a corner shrub. These can be placed together to provide several different configurations. You could use them in any type of wargaming where you need obstacles in the way of advancement or ranged attacks.
This augments my previous city street and urban environment sets that are located here.https://www.thingiverse.com/thing:2534898
and located here with additional pieces.
