Font Modification Steps:

1. Import the blank fan into Bambu Studio software and repair any stray edges.

2. Enter the characters to be engraved (as it is a curved surface, each character needs to be engraved individually).

3. Perform a Boolean operation (difference) between the characters and the fan.

Effect:

4. Repeat the same steps (steps 2 and 3) to engrave other characters.

5. Then separate the entire parts into objects.

6. Stitch together the small pieces resulting from the Boolean operation on the fan.

Create a yellow add-on block with dimensions of (5mm * 2mm * 0.8mm), then combine the red, yellow, and green parts, resulting in the following effect:

7. Modify other fonts in turn to complete the customization.
