Some modification of the rubik's cube post

Question

I read the question concerning the rubiks cube and that seems fine for my intention. However, i have no real cube shape, but 4 "columns" and 3 "rows" and 3 "steps" in the depth.

Can this Code posted by Max Snippe can easily be modified to achieve this? I am a complete beginner in the 3d Plot and just asked myself it this is an easy modification or too complex? EDIT: And to modify it in a way to stretch other dimensions that the outer shape look like a cube?

Code:

\documentclass[border=5pt,tikz]{standalone}
\usepackage{tikz-3dplot}
\usetikzlibrary{3d}
\begin{document}
\foreach \myPsi in {90,100,...,170}{
\tdplotsetmaincoords{70}{\myPsi}
\begin{tikzpicture}
    \clip (-8,-6) rectangle (8,6);
    \begin{scope}[tdplot_main_coords]
        \draw[step=2cm,canvas is yz plane at x=4] (-4.01,-4.01) grid (4,4);
        \draw[step=2cm,canvas is xz plane at y=4] (-4.01,-4.01) grid (4,4);
        \draw[step=2cm,canvas is yx plane at z=4] (-4.01,-4.01) grid (4,4);
    \end{scope}
\end{tikzpicture}
}
\end{document}

Many thanks in advance.
