This is a 3D printing color card model designed for quickly testing consumables and clearing out leftover materials. Inspired by the exploration of the aesthetic of consumable textures, it features built-in streamlined wave textures and concentric gradient fills, which not only visually showcase the true colors of the consumables but also clearly present the details of layer lines and the refraction of light and shadow. The model requires minimal consumables and short printing time, making it ideal for clearing out leftover materials in the printer before replacing them, and it can be easily completed without the need for supports
