Here's a chest that you can use to experiment with 3D Printing and rendering. Included there's the Marmoset Toolbag file that I used to render the image you see. It comes along with 4 textures set, all of them in 4k.

It's a sculpt that was made in Zbrush(exported in FBX, OBJ, STL format).It's made for 3D printing and CG work ( I made different versions). There's one called Devil_Printable ( there are STL, FBX, OBJ format ), you can use this model to print it.

Usage : This is a model with 4 differents ID's on it. Which means that whatever software you are using to render it, you'll need to use 4 differents materials. All of the maps you'll need to create nice renders are included.Base Color Normal Roughness Height

Hope you'll have fun with all of that !
