In a conceptual work made in college, a small part of the modeling refers to some excellent work cases, but most of them are original designs, and some learned technologies are applied as much as possible.
This conceptual product design has been in the folder for a long time, and I have always wanted to move it to the platform. Finally, I presented it with 23 years of small tail, urging myself to update my works in the coming new year.
(For the specific function explanation of the product, you can watch the last typesetting drawing, which contains written instructions)
