作者的版本需要大量胶水，但是我比较懒，不喜欢用胶水，所以做了这个没有胶水的版本。但是需要一些支撑，这个支撑拆除也非常简单大概需要30秒时间就能拆除完。请放心打印，预留的洞是为了方便拧螺丝预留的，总共两个版本，一个版本需要少量胶水，一个版本不需要胶水，这个可以根据自己的需求做选择。

The author's version requires a lot of glue, but I'm lazy and don't like using glue, so I made this version without glue. But it requires some support, and the removal of this support is also very simple and takes about 30 seconds to remove. Please feel free to print. The reserved holes are reserved for the convenience of tightening screws. There are two versions in total. One version requires a small amount of glue, and one version does not require glue. You can choose this according to your own needs.
