Labyrinth Long Rails Metal Sign

About the Long Rails design

Thin walls run only in three directions here, flat and tilted to match the sides of the outer triangle, so every turn in the passages breaks at a sharp or wide angle. At the center sits an empty upright triangle, a smaller echo of the outline, and its base continues as one long straight rail that stretches most of the way to the left edge. Tight hooks curl along the bottom row, while longer diagonal runs stack up the right slope like rungs.
