Rockwood Classic 8 SRW block

I am building a retaining wall. I wanted to optimize the curve, so instead of going out and playing trial and error with 80 pound blocks, I thought I'd build it in tinkercad. So that's what this is. It's a scale model of a single block. You can print as many as you need to play like Lego or you can put them in your digital environment and play with the angles. I found that an angle of 11.25 degs results is a nice smooth 7-block curve with a radius of about 6'-3.5". Have fun!
