This is my major assignment for the reverse engineering elective course. The shell of the work comes from model: 4728422. But since this project does not allow remix, my project only contains the inner part, which I obtained by reverse engineering and modifying the pattern. The front is Genshin Impact font of Southeast University (from video https://www.bilibili.com/video/bv1qw411k7un）, and the wind logo of Genshin Impact; on the opposite side is the school logo of Southeast University. 中文省流说明：东南大学《逆向设计与制造实践》大作业，文件只有内核，外围去https://www.thingiverse.com/thing:4728422下载。通过逆向得到的内核形状，通过逆向得到的花纹。 The attachment contains the files required for reverse design. 附件包含了逆向设计所需文件。 Reverse Engineering：Geomagic design X
