Today's Strange-Shaped Sunday puzzle is a Ring-Ring (No Squares) (Cube) because I thought that was funny.

Rules: Draw non-square rectangles by connecting the centers of edge-adjacent cells such that all empty cells are used by at least one rectangle. The rectangles may overlap, but they must not share edges or corners.

(A rectangle is a closed loop where all internal angles are 90°. A rectangle may use one, two, or all three visible faces of the cube. In the case where a rectangle visits all three faces, it will only have three internal angles, as moving from one face to another does not constitute a turn. A "square" is measured by number of cells travelled through between each internal angle---that is, a square is any loop with all equal side lengths, regardless if three or four sided).
