How to create a mesh with given node distances?

I have a question regarding MATLAB mesh creation. I was trying to create a 3-dimensional mesh with specific distances between each node (such that the resulting mesh is made of cubes, so node distances are constant throughout the whole mesh). Is there a way to do it? When I was reading through the mesh and meshgrid documentation but unfortunately there does not appear to be a method written out in there.

The mesh should look like this. It is a 7-cube mesh, with the 7th cube being in the interior of the mesh. (the bottom cube is cut out because I do not intend to have an 8 cube mesh. Just pretend that the sliver isn't there)

Thanks in advance!
