What you have is a Pharos, fully modded by Will's mod package.
The Blue Acrylic circle, should be a clear one, when the blue protective cover is removed, but it doesn't have to be removed. You adjust the grind by turning that knob with pointy arrow. Clockwise for finer, counter clockwise for coarser. The lines on the acrylic piece serve as reference point. You lift the rubber flap in the middle to insert beans. You can hold the Pharos from the center or from any of the 3 columns. Once you are done grinding, lift the Pharos and remove the stainless steel catch cup from below.
