Detailed Installation Instructions（详细的安装说明）：

See below（下滑页面后查看）

Special Instructions（特别说明）：

Component appearances may vary with updates; images are for illustrative purposes only.

随着版本更新，模型一些部件的外观会随之改变，页面上的图片仅作为参考。

Functionality relies on filament friction and elasticity; performance may vary with different filaments. The base cover and resistance ring primarily determine the rewinding angle. The prototype was printed and tested using PolyLite (logo color).
The 6-blade resistance ring generally yields satisfactory results. Optimal resistance is achieved when the inner bushing's spiral ring is fully compressed before the resistance ring begins to rotate.
For insufficient resistance, consider using a higher-blade-count resistance ring.
For excessive resistance, trim the resistance ring blades.
Newly printed components exhibit higher resistance; manual rotation for a few cycles is recommended before initial use to ensure smooth operation.
Avoid excessively smooth or brittle filament for the base cover and resistance ring (standard PLA is suitable).
本模型的功能实现依靠耗材丝的摩擦力及回弹力，所以不同耗材打印的模型表现会有一些差异，决定回卷角度的主要配件为基盖和阻力圈，实验模型采用的是PolyLite（标志颜色）进行打印和测试。
默认情况下6叶阻力圈即可实现满意效果，阻力合适的标准表现为转动轴套时，内轴套的螺旋圈基本压缩完全时阻力圈开始转动。
如果阻力过小可以选择打印更多叶片的阻力圈。
如果阻力过大可以剪掉阻力叶片来降低阻力。
新打印的配件阻力相对较大，建议手动转几圈使其磨合到相对稳定的状态后再开始正式使用。
最后建议不要使用过于光滑或者过于脆的耗材丝打印基盖和阻力圈（普通PLA就行）。

Operational Issues（使用问题）:

Impact on Print Quality（是否对打印质量产生影响）:

Extensive testing revealed no discernible impact on print quality.
If concerned, manually disable the rewind function during printing.

经过我一段时间的使用和测试，没有发现有明显的影响，至少我没有明显感觉出来。如果你担心这个，在打印时可以手动停用回卷功能。

Extruder Load（是否会对挤出机带来较大负担）:

Given the extruder's considerable tension—capable of filament breakage—the added load from the rewinding spool holder should be negligible (further mitigated by the spool radius's moment amplification effect), at least based on my testing.

挤出机的拉力是很强大的，甚至能将耗材丝直接拉断，所以回卷架的这点负担应该不成问题（而且还有料盘半径的力矩放大作用存在），至少在我有限的测试中一切都是正常。

Disabling the Rewind Function（停用回卷功能）：
1.For temporary deactivation, press your thumb against the shaft cover and pull the claw or threaded bushing outwards by 10 mm (a retaining clip prevents slippage).
   临时停用，用拇指顶住轴盖，将抓套或螺纹套向外拉出10毫米即可（不用担心滑落，此时还有一层保护卡扣存在）
2.For extended periods of disuse, remove the resistance ring; it then functions as a standard spool holder.
   长期停用，拆除掉阻力圈，即可当做普通料盘架使用，至少料盘不会晃来晃去
3.For permanent deactivation, remove all components.
   永久停用，全部拆掉即可

Adjusting the Rewind Angle（调节回卷角度）：
Adjust the resistance level, as detailed in the special instructions.
调整阻力大小即可，见特别说明中的描述
Filament Installation and Replacement（耗材的安装与更换）:
During filament feeding, partially extend the claw or threaded bushing (approximately 10 mm), placing it in pause mode. Fully extend it only after feeding is complete, eliminating the need for continuous manual filament feeding (due to the rewind mechanism).

可以直接安装，也可以把爪套或螺纹套取下后安装，另外进料时可以先不把抓套或螺纹套推到底，留10毫米左右距离，即置于暂停模式，等进料完成后再推到底，这样就不需要一直用手推着耗材丝了（因为有回卷力）。

Removing the Central Shaft（拆卸中心轴）：
Sufficient force will dislodge the shaft, even with the retaining clip.
即便在有搭扣的情况下，用足够大的力量是可以直接拔出

Known Issues（已知问题）：

1.The rewind function generates some noise, deemed acceptable.
   回卷功能使用中会有一定噪音，但我就觉得在可接受范围内。
2.Over time, resistance ring wear may reduce the rewind angle.
   阻力圈在使用一段时间后阻力会一定程度的变小，因为磨光滑了，回卷角度会缩小。
3.Near-empty spools may not fully retract filament due to reduced radius and rewind distance, but this is inconsequential.
   在耗材丝剩余不多的情况下，无法完全收紧耗材（因为半径小了回卷距离就短了），但这并没有什么不良影响。
4.Claw bushings may fit tightly onto spools at their minimum supported size, requiring force for installation.
   各种规格的爪套，安装在其支持尺寸下限的料盘时会比较紧，需要用力才能装入。

Installation Instructions（安装说明）：

Important: Before installation, insert the central shaft into the inner bushing to verify smooth rotation. Address any imperfections or apply petroleum jelly for easier rotation (note that warping during central shaft printing may cause binding).

特别注意：在安装开始前，请将中心轴插入内轴套中，测试旋转是否顺滑，如果不顺畅请处理掉不平的地方或抹凡士林使之旋转顺滑（特别注意，打印中心轴时翘边也会造成卡顿）。

Important Note: Step 8 requires rotation to align the bottom retaining clip!

特别提示：第八步需要通过旋转对齐底部的卡扣!
