Steps to texture the stl file imported into 3done:

1. Open the model: Use 3D printing software to open the imported STL file.

2. Prepare a texture image: Select a texture image. The file format needs to be consistent with the printed model. Common formats include JPEG and PNG. It is recommended to use high-resolution images.

3. Import the texture image into the software: In the 3D printing software, open the texture image, then import the texture image into the software and adapt it to the printed model.

4. Set the texture: Find the rendering setting option of the texture in the software, and set and adjust the texture accordingly to obtain the desired effect.

5. Export and save: After completing the texture, export and save it into a file format supported by the printed model.
