🧵 改进款缝纫机机顶线轴架，适配家用缝纫机使用大型线锥。
Upgraded Top Spool Holder for Home Sewing Machines, Compatible with Large Cone Threads.

更高的强度：杆体更坚固，不易断裂。

Enhanced Strength: The rod is stronger than my early version, and easer to print.

通用线轴适配：底部设有限位台阶，可稳固卡住不同尺寸的线轴。

Universal Spool Compatibility:I design a circle step at the base that allows different-sized spools to be securely held.

两种连接方式：适配胜家、兄弟（Brother）M370等主流机型。

Dual Connection Methods: Compatible with Singer(Using Type-1 file)、Brother M370 (Using Type-2 file) and other popular models.

安装说明：
Installation:

底部预留安装孔，直接套在原有的线轴杆上即可。首选安装位置为Type-1，如果没有这根杆子（例如M370），则可安装在Type-2位置。
Simply place it over the machine's original spool pin via the hole at the bottom.The primary mounting position is Type-1. If this rod is not present (e.g., on the M370), it can be installed at the Type-2 position. 🔧

（原装线轴杆参考尺寸：直径5.5毫米，长度50毫米）
