增加了4010风扇位辅助x轴电机散热风扇位，不过我觉得没必要加散热这位置，因为不算热相对其他部位

带装饰外壳。如果要用装饰外壳，需要胶水或自攻螺丝固定风扇，不使用则用m3x15平头螺丝加螺母即可

An additional 4010 fan position has been included to assist with the cooling of the x-axis motor, but I don't think it's necessary to add a fan at this position because it doesn't get as hot as other parts. If you plan to use a decorative casing, you will need to use glue or self-tapping screws to secure the fan. If the decorative casing is not used, then you can simply use m3x15 flat head screws and nuts for installation.
