Hello,
I took the base model from the source one and added colors in bambu studio.
That's it, no geometry modifications at all. (hoping I can actually post that ?)
While not perfect, I should have done a pretty good job and you can now try printing that in color.
I'm sure it can be perfected though, don't hesitate!
I did not actually try to print it yet, 1d13h at 0.2mm scares me. View that as ground work if you wanted to give it a go with that model.
I also saw this other post that looks to be the same source in thingiverse except this one doesn't give credit. I'm not sure if that's the original author or not.

Sword could probably switch to white, I did it for ams 4 colors and couldn't add silver.
The author remixed this model.
