A pack of nine game-ready wrenches of different dimensions, available on Fab in .fbx format on the following link:

Each model has its own texture in 2k format with its own measure for every head.
I used Blender and Substance Painter for this project, with a couple of tests on Unreal Engine to make sure they were all right.
Feel free to ask any questions if you have any!
