Awesome, thanks for the reply..just set mine up 8 inchesGreat question, Shack. 8", all day long! I think the only thing I would do different is make my squares smaller. I don't know how I screwed that up, but I meant for them to be about 2", but they came out at 2.25". I think a bit smaller than 2" would have been my sweet spot. 2.5" - 2.75"
