I am trying to build a maze similar to the one shown below.

maze

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.

If you just want thet two maze walls touching you could do this in object mode without the need to edit anything.

With a default scene resize the cube as required

enter image description here

when finished ctrla and reset all of the transforms

enter image description here

Turn on snapping and set snapping to vertex

enter image description here

Select the 3D cursor and snap as shown

enter image description here

with the cube selected rightclick and choose origin to 3D cursor

enter image description here

With the cube selected press shiftd to make a copy and immediately rightclick. This makes a copy and leaves it in place.

Select one of the cubes and F3 and type Mirror and choose the X axis

enter image description here

enter image description here

rz22.5 to rotate the object 22.5 degrees

and then the same with the other cube but use -22.5

enter image description here

You now have the shape and can copy and rotate as required.

Create the following shape using NURBS curves. Then convert it to mesh, solidify and use array modifier.
