Hello,
I took the base model from the source one and added colors in bambu studio.
That's it, no geometry modifications at all.
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 to remix further!
I tried to print this model and failed supporting the sword, you really need strong supports for the bottom of the sword (maybe don't go for trees).
Please use your own profile I only did the coloring and kept the default stuff.
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.
