Industrial Pipes and Gears Vector QR Code for Posters

About this design

A scatter of navy and rust red pipes, gears, valves and elbow joints sits on a clean white background, drawn in flat vector shapes. Square frames with round lens-like hubs at their centers disguise the three finder squares, one in navy and two in red. Chunky pipe segments, small bolts and wheeled parts carry the modules between them. Strong dark-on-white contrast and evenly spread detail keep the pattern readable, and the red accents add a rail workshop feel.
