tikzpicture no cabe en el documento

Question

Tengo un código en el que uso algunas miras para dibujar algunas figuras en 3D.
Pero el resultado no cabe en el documento independiente.
\hbox{*}y \vbox{*}no ayuda.

¿Que tengo que hacer?

Debería verse así:

\documentclass[margin=5pt]{standalone}
%\documentclass{article}
%\usepackage[margin=15mm]{geometry} 
\usepackage{tikz} 

\begin{document}

\def\a{1}
\def\h{0.2}
%%%%%%%%%%%%%%%%%%%%%%%%%%
\hbox{\vbox{%%%%%%%%%%%%%%%%%%%% 
%%%%%%%%%%%%%%%%%%%%%%%%%% 

\begin{tikzpicture}[font=\footnotesize,
very thin,
%line cap=round,
x={(1,0,0)}, z={(0,1,0)}, y={(0.5,0.5)}, 
every label/.style={text=black!1},
]

\coordinate[label=below:A] (A1) at (0,0,0);
\coordinate[label=below:B] (B1) at (\a,0,0);
\coordinate[label=below:C] (C1) at (\a,\a,0);
\coordinate[label=below:D] (D1) at (0,\a,0);
\coordinate[label=below:A] (A2) at (0,0,\h);
\coordinate[label=below:B] (B2) at (\a,0,\h);
\coordinate[label=below:C] (C2) at (\a,\a,\h);
\coordinate[label=below:D] (D2) at (0,\a,\h);

%% straight %%%%%%%%%%%%%%%%%%%%%
\foreach \n in {0,...,9}{%%
\begin{scope}[transform canvas={shift={(0,0,\n*\h)}}]
\draw[] (A1) -- (B1) -- (C1); 

\ifnum\n=9 \draw[fill=white] (A2) -- (B2) -- (C2) -- (D2) --cycle; 
\else \draw[fill=white] (A2) -- (B2) -- (C2);  \fi
\foreach \P in {A,B,C} \draw[] (\P1) -- (\P2);
\end{scope}
}%%

%% skew  %%%%%%%%%%%%%%%%%%%%%
\begin{scope}[transform canvas={shift={(12*\h+\a,0,0)}}]
\foreach \n in {0,...,9}{%%
\begin{scope}[transform canvas={shift={(-\n*\h,0,\n*\h)}}]
\draw[] (A1) -- (B1) -- (C1); 

\ifnum\n=9 \draw[fill=white] (A2) -- (B2) -- (C2) -- (D2) --cycle; 
\else \draw[fill=white] (A2) -- (B2) -- (C2) -- (D2);  \fi
\foreach \P in {A,B,C}{  \draw[] (\P1) -- (\P2);  }
\draw[fill=white] (B1) -- (C1) -- (C2) -- (B2) --cycle;
\end{scope}
}%%
\end{scope}
\end{tikzpicture}

Aquí tienes una manera de evitar transform canvasy agregar la transformación cada vez que usas una coordenada.

\documentclass[margin=5pt]{standalone}

  \def\h{0.2}
  \def\makecoords{%

        \makecoords
        \draw[] (A1) -- (B1) -- (C1); 
        \ifnum\n=9 \draw[fill=white] (A2) -- (B2) -- (C2) -- (D2) --cycle;

No estaba seguro de para qué servía el \vboxin an \hbox, así que lo eliminé porque parecía no cumplir ninguna función.
