This one was a lot more challenging than the others from the series. Since the design was going to be 3D printed, I wanted the parts lines to accentuate the design rather than to make it look like its glued together. The print is around 16 parts and took around a day or 2 complete.

[翻译] : 这个系列的第五个作品比之前的更具挑战性。由于设计将采用3D打印，我希望零件线能够强调设计的美感，而不是让它看起来像是用胶水粘合的。这个模型大约由16个部分组成，完成它大约需要一两天的时间。stl文件在这里可以下载：
