Grinding Wheel Dressing tool

I just made this quick tool to hold the 3/8" diamond dresser tool 3191 from Little Machine Shop. The orientation is is designed to straighten out my RH grinding wheel. It uses a 1/4-20 bolt and a 7/16 hex square nut. I printed it a 60% infill, but I am sure 40 is fine; 20 might be okay too...
