All Pass Candy - Book-Like Box

It is popular in the Department of Financial Engineering and Actuarial Mathematics of Soochow University in Taiwan to distribute "All Pass Candy" at the end of the semester. The candies are packed in book-like boxes to bless everyone who passes the exam. Students used to make it by hand, but now I use 3D printing to make it. 2021/11/8Added a new printing configuration with the word "歐趴" on the back of the book.
