Grey is what most engineers reach for when they want to inspect a part rather than admire it. Surface flaws, seams and overhang sag all show clearly against a neutral tone, making this spool a sensible default for fit checks, tolerance trials and enclosure drafts. It also finishes well, since sanding marks are far less obvious than on black and primer barely shifts the colour. The tag on the spool saves a menu dive on printers that support it, and the high-flow formulation brings a test iteration back quickly enough to keep a design session moving.
