My mom does a woodcarving process kind of like this. Her stuff is really detailed so this would likely be a cinch for her. Xmas is coming so maybe I could ask her. Tho I imagine the forward version would be needed. I'll check for a source. Sometimes the artists put their .3ds/.mqo or whatever files on their site.

....or if its a CAD type file, I'd take it to my cnc machine to make decals
It is indeed made with CAD, judging by the tags on Pixiv, but I didn´t see any link on his Pixiv profile, and the only other site with his name on Google was a blog about cars
