According sam's work in the second round of the Q version is still very rough, and many details are not very good, but it is better than the previous firefly, and it feels good. Very good printing, it is recommended not to change the support angle threshold, otherwise the surface quality may be relatively poor, the peripheral support is easy to remove, it is recommended not to remove the bottom support. The size of 140 is closer to the original size and can be enlarged as required. If the zoom is around 200, the personal feeling is OK.
