I would like to model a splint for a paralyzed hand. I have the hand scanned in and turned into a surface model. I have been making physical models but I want to make a 3d printed steel splint model that has and organic cell shape pattern. I know you can use textures and rendering to get that to happen visually but I want this to be in the actual physical model. I can go in and model each hole individual but I am wondering if anyone knows of a better way that looks more natural.

Kind of like the picture I inserted here. The chair is the effect I would like on the splint on the hand. I also have modo 901 As software. Any input is welcome.
