This is a stone tile top cap created from a picture and somewhat matching that picture for texture. The reasons for the differences from the picture are that I truncated some of the ends, reduced the element numbers and also had to resize to have a 2x2 inch layout since the picture was more rectangular. This is a top cap that can be placed on openlock bases that can be obtained free from the following website.

The top cap can be increased in size by 25% to be a true tile size. There is a true tile size at 1 1/4 inch 2x2 as well with openlock. The free openlock Wyloch (true tile) size base can be obtained from this link. http://www.heroshoard.com/true-tiles
You could also use mine which are already set to either base size.

This is a rather large file for a tile. The reason being that I tried to do as much of the texture detail as I could. It may take a little bit to load, but it will print well.
