Textured Barrier for 3-path Dice Tower

This is a textured version of @cxquek (http://www.thingiverse.com/Cxquek/about)'s barrier for @bainite (http://www.thingiverse.com/bainite/about)'s 3 Path Dice Tower v2.

The fact that I named 2 other makers in the first sentence so be obvious - I didn't create anything here ;)

I used the same pattern from texturelib that @bainite (http://www.thingiverse.com/bainite/about) used on his tower. My stones came out smaller though because of some scaling. Now that I figured out a relatively do-able workflow, I'll probably do another version that better matches.

A couple of notes:
- I had a bear of a time adding depth. All the F360 info out there suggests using "Offset Faces", but it would error most of the time. I finally hit on getting it to work by trying to negative extrude the underlying face first, then using offset faces with a number less than the displayed radius OR "-1" (it varied).
- This isn't primetime ready - there's a couple of spots where the intent didn't meet execution.

Mad props to both @bainite (http://www.thingiverse.com/bainite/about) for his original inspiration and @Cxquek (http://www.thingiverse.com/cxquek/about) for taking the plunge to create the barrier. I printed the tower for a friend and had given some time and thought to a barrier at his request, but I didn't give enough of either to make any progress heehee.

Side note - I thought I had it beat using 3D Builder's "emboss" feature, but the stones would consistently have tops (outside faces) smaller than the base and angles created by the size diff, the mortar space was much to big for my liking, and the actual depth didn't seem to change.

I gave Meshmixer a run too - man, me and MM just do not speak the same language. I'm sure someone with some MM skills could do it, just not for me.
