随着A1mini机器增多，很多都是单机版本，A1mini原设计线轴架在机器的右后方，个人觉得比较占用机器的尾部空间，并且在打印中由于重心不平衡，在长时间打印后，机器会旋转，而且原线轴架只能放置一卷耗材，每次换料需要从下往上穿线比较麻烦，既然已经是单色版本的机器，干脆把特氟龙管子也去掉了，减少一些喷头移动的阻力，经过多次设计修改和司机打印测试，最终方案已经上传：

With the increase in A1mini machine, many are single version, A1mini original design spool holder in the right rear of the machine, I feel more occupied machine tail space, and in the print due to the imbalance of the center of gravity, after a long time to print the machine will rotate, and the original spool holder can only be placed on the roll of supplies, each time you need to change the material from the bottom up to threading is more cumbersome, since it has been a single-color version of the machine Since it is already a monochrome version of the machine, simply remove the Teflon tube as well to reduce the resistance of some nozzle movement, after many design modifications and driver printing tests, the final program has been uploaded:

设计打印说明：

尽管内部设计了双层壁厚加强打印强度，注意：由于线轴架现在改为顶部，为了确保安全使用，务必确保打印材料的耐温和层间强度，请使用优质耗材打印，我使用的是PETG耗材，我拿其中一个手工尝试掰断它，实际没有成功：

Design Printing Instructions:
Despite the internal design of the double wall thickness to strengthen the print strength, note: as the bobbin holder is now changed to the top, to ensure safe use, be sure to ensure that the print material temperature resistance and interlayer strength, please use high quality consumables to print, I use PETG consumables, I take one of them manually to try to break it, the actual did not succeed:

提供两个版本：一个双料盘位置线轴架：

Two versions are available: one with a double bobbin position spool holder:

顶部插入一根特氟龙管用来减少耗材摩擦

A Teflon tube is inserted at the top to minimize friction with the consumables.

另一个是单盘位的线轴架：

The other is a single reel position spool holder:

安装过程如下：

The installation process is as follows:
