Hi,
I've published a new worldedit command "//maze" by doing a fork here :
https://github.com/biggrizzly/Minetest-WorldEdit
It allows to create one or several mazes in a single command.
### `//maze <node_wall> <node_path> e(lliptic)/r(ectangle) m(ulti)/s(ingle) path_width f(ixed)/r(andom)`
Creates a maze in the current WorldEdit region with `<node_wall>`. The exit path can become viewable using `<node_path>`. The maze can be `elliptic` to create an elliptic tower instead of a `rectangle` tower. If `multi` is selected, the tower will be filled with several mazes of 4 blocks high each. The `path_width` value determines the number of blocks used for the path width and the walls width either. `fixed` means that the entrance will always be at the same place, and the exit either.
//maze stone stone elliptic single 1 fixed
//maze stone cobblestone r m 3 f
Here are some simple examples :
