For a 7x7x7 a cube shape with all the same size cubies, is not a trivial construction. This is mainly by the fact if you turn the 7x7x7 cube with same size cubies, the corners will overhang when turning 45degrees.
An other options is to make a 7x7x7 sphere shape or pillow shaped, but this will not a practical form to play with.
To overcome this mechanical difficulty, we could make the inside cubies a bit smaller. see pictures below. Now at a 45 degree angle the corner is supported by the inner mechanism.
