cylinder(h = shank_length, d = shank_diameter, center = true, $fn = 64); OpenSCAD で、規格に準じた M8 サイズの六角ボルトを作ってください。 ねじ山自体は省略してよく、円柱のシャンクで構いません。 寸法は以下に従ってください: - 頭部は六角柱で、対辺距離(across-flats)13mm、高さ 5.3mm - シャンク(軸部)は直径 8mm、長さ 30mm の円柱 - ボルト全体の中心軸は +Z 軸方向 - 頭部の底面が原点(z=0)に来るように配置し、シャンクは z<0 側へ伸ばす 完成したコード全体を ```openscad ... ``` のフェンスで囲んで出力してください。コードのみで、追加の説明は不要です。
