Three-color Bookmark - Plum Blossom With You

Hello everyone:
Here is the second bookmark I made. I hope you can give valuable suggestions. New works are being made faster, so please stay tuned! Please follow!

Notes:
Please configure the 3-color AMS multi-color printing kit correctly. If you don't have AMS, please set a pause at the color change layer and manually change the filament.

Negative parts have been added. By default, it will be sliced into a rounded corner punched version. If you need a right-angle, non-punched version, please delete the negative parts before slicing.
About filament:
Bambu Basic filament was used during testing, and the effect was ideal. For white, do not choose filament with low transmittance (T-value), such as Bambu Lite white filament, frosted, matte, or silk-textured filaments, as they will significantly reduce light transmittance. Absolutely avoid them. Red and black filaments are already in the lower layers, so the requirements are relatively low.
About the 3mf for this image:
The image was first drafted with AI, then color-adjusted with Photoshop, then an STL model was generated with HueForge, after which rounded corners and holes were Boolean cut with Blender, and finally imported into Bambu Studio to set basic parameters and filament colors during slicing. It's only complete after saving the 3mf.
Filament:
Bambu Lab PLA Basic Black Transmittance distance: 0.6
Bambu Lab PLA Basic Jade White Transmittance distance: 6.2
Bambu Lab PLA Basic Red Transmittance distance: 3.7
Detailed color change method without AMS:
Start the bottom layer with black
Layer 7 change to white;
Layer 13 change to red;
Layer 20 change the remaining part to white.

Everyone is welcome to post the pictures you want in the comment section. If I see one suitable for a bookmark, I will make it for you as soon as possible.
