这是一个比较节省占地空间的顶部耗材支架，除了本文件内的3个零件外，你还需要打印作者“达文西”制作的A1Mini版外挂耗材支架。

注意，轴心和轴帽必须打印本文件内的。

注意事项：文件内的轴心必须是是平放着打印，这样才能获得足够的强度，除非你对你的耗材性能非常有信心，否则我不建议竖着打印。

在安装顶部支架时我建议先装靠后的单个螺丝，然后把支架卡进滑轨再安装其他两个螺丝。

This is a relatively space-saving top consumable bracket, in addition to the 3 parts in this document, you also need to print the A1Mini version of the external consumable bracket made by the author "达文西".

Note that the shaft and shaft cap must be printed in this document.

Note: The axis in the document must be printed flat to obtain sufficient strength, unless you are very confident in the performance of your consumables, I do not recommend printing vertically.

When installing the top bracket, I recommend installing the single screw at the back first, then clamping the bracket into the slide rail and installing the other two screws.
