K cup storage rack

The original by carguy87 was not wide enough to fit my k cups and does not have a stopper to prevent the cups from sliding out the back. My version is made for k cups that measure 51 millimeters lip diameter and I also thickened the base layer to add stiffness. The stopper blocks allow you to mount the rack vertically as well. I added hex holes to reduce material use and speed up the print time slightly.
