画一个多通道板？

知道如何在 LaTeX 中绘制这个吗？可能吗？下面的 MWE（来自 Hugues Vermeiren 的示例代码）仅生成一个短圆柱体。我不知道如何进行剪切，所以我可能会放弃它并在整个正面画一些小孔。但如果有人可以剪切，请提前致谢。

    \documentclass{standalone}
    \usepackage{tikz}
    \tikzset{Persp/.style={scale=2.8,x={(-0.8cm,-0.4cm)},y={(0.8cm,-0.4cm)}, 
    z={(0cm,.5cm)}}}
    \begin{document}

    \begin{tikzpicture}[Persp]
    \def\h{.75}% cylinder length
    \def\a{35}
    \begin{scope}[rotate=-90]
    \foreach \t in {140,320}
    \draw[black, very thick] ({cos(\t)},{sin(\t)},0)--({cos(\t)},{sin(\t)},
    {2.0*\h});
    \draw[black,very thick] (1,0,0) % front outer circle
    \foreach \t in {5,10,...,360}
    {--({cos(\t)},{sin(\t)},0)}--cycle;
    \draw[black,very thick] (.8,0,0) % front inner circle
    \foreach \t in {5,10,...,360}
    {--({.8*cos(\t)},{.8*sin(\t)},0)}--cycle;
    \draw[black,very thick] (1,0,{2*\h}) % bacl outer circle
    \foreach \t in {10,20,...,360}
        {--({cos(\t)},{sin(\t)},{2*\h})}--cycle;
    \foreach \t in {5,10,...,360}

当我在等待学生的考试成绩时，我开始画这个。

这是一些相当临时的代码...请不要评判我。

无论如何，输出

在此处输入图片描述
