Description
This is a printable texture that you can use to press into cheap dollar store foam core to create a rock texture. Bunched up tinfoil is traditionally used for this but I wanted something a little more solid that wasn't as wasteful.
I started with this rock texture image:

I converted the image to 24-bit BMP using Paint.Net

I used Sketchup Make 17.2 with the following extensions to create a 3D mesh from the black and white image.

Update
I can press it into foam to make a stipple pattern but the detail is far too small. I'm going to make a new item using the "Bumpy" script for Sketchup.
