I am trying to build a maze similar to the one shown below.
This was made with basic urdf models on pybullet physics simulator. However, if you look at it closely, some pair of walls have gaps in between them and some don't. I tried many ways to get rid of them but it's very inconsistent for some reason. Instead I'd like to make the same shape on blender as a single .obj file. Any links or suggestions would be much appreciated.
