我个人比较喜欢更直立姿态的支架，所以自己设计了一款适用于12.9寸的iPad Pro支架，前方有小槽可以放置App了Pencil，后面有小凹陷用于放一些零零碎碎。
非常稳固，打印也十分简单，欢迎大家下载。

I personally prefer a stand with a more upright posture, so I designed a 12.9-inch iPad Pro stand myself. There is a small slot in the front for storing App Pencil, and a small depression in the back for storing some small pieces.
Very stable, printing is also very simple, welcome everyone to download.
