Wanhao Di3/Cocoon Create scraper tool hook

Another hook to keep your scraper tool close-at-hand. I tried this one by ananag (http://www.thingiverse.com/thing:1279968) but found I couldn't get my scraper over the end of the hook. Rather than modify the design, I decided to try designing one in OpenSCAD. I used ananag's design as inspiration (specifically how it attaches to the printer), but used a scaled cylinder, quarter torus and hemisphere for the hook.
