Customizable Calf Roller

I crafted this based on firsthand experiences. As a runner myself, I've seen one of these before - a common sight in every serious athlete's routine. After a tough workout or game, you roll these on sore muscles while applying pressure, and they help alleviate soreness. At running events, people inevitably lose them. If you try to write your name on them with a Sharpie, the ink ends up on your sweaty legs instead. Since these devices all look identical, people frequently accidentally take each other's by mistake. To print this design, simply combine Parts 1 and 2, along with ten of the pieces labeled "Blank" or "Letter" ("A", "B", "C", etc).
