Koi

Supports require some force, and needle-nose pliers are needed

The base is optional

Requires self-coloring

White-backed koi coloring tips in the picture:
1. First, apply one coat of black marker to the areas that need to be blackened

2. After the first coat dries, apply a second coat, and reapply black marker to areas that need to be particularly dark

3. For the gradient areas, apply five coats of white marker (gray is also acceptable), and give the eyeball area special treatment once

4. Outline the lines with a white marker once

If you want to adjust the model, supports can be reduced appropriately, but do not just use the default, you must manually add supports, otherwise it is prone to spaghetti
