About this 3D model
The original size of the logo is large to start off with and will need to be resized depending on where you are planning to put the object. Kaiba had this logo on his trench coat collar, belt buckle, etc. so you can easily measure and resize the object. The dimensions and time I provide are what I used to create some keychains and are also about right for the logo on his trench coat (depending on the pattern you are using/draft).
