A1 mini Z-axis lead screw knob/handwheel/runner

A1 mini Z-axis lead screw top knob/handwheel/pulley, allows manual rotation of the Z-axis to raise or lower the height position of the X-axis when the stepper motor is in an unlocked state. The rotation of the knob can also be observed during the printing process, which adds to the enjoyment.Need to remove the top cover and use this model instead“https://makerworld.com/zh/models/62015#profileId-64497”

A1 mini Z轴丝杆顶部旋钮/手轮/转轮，可以在步进电机解锁状态下手动转动Z轴以便提升或降低X轴高度位置，也可以在打印过程中看到旋钮转动，这是一种乐趣。需要去除顶部封盖，改用这个模型。
