A1mini prints to a high Z-axis swing seriously, and the model is easy to stagger. If you seal the box, you can use this model to fix it. The fixed height can be adjusted. I hope it will help you. There are length and length adjustment bolts in the step file.
A1mini打印到高处Z轴摆动严重，模型容易错层，如果你封箱了就可以用这个模型固定一下，固定高度可调节，希望对你有所帮助。step文件中有长短调节螺栓。
