在足球比赛中裁判用的红黄牌，一个非常简单的模型，采用了国际足联的标准尺寸（网上查询的），稍后还会上传一个中超版本（尺寸稍小一些），感兴趣可以下载使用，和朋友踢球的时候拿出来一定非常有意思，你也可以自己用solidworks画一个，非常简单，祝大家玩得愉快！

The red and yellow cards used by referees in football matches are a very simple model that uses FIFA's standard size (found online). Later, a version of the Chinese Super League will be uploaded (slightly smaller in size). If you are interested, you can download and use it. It will be very interesting to take out when playing with friends. You can also draw it yourself using Solidworks. It is very simple. Wishing everyone a pleasant time! (Machine Translation)
