Triple Gang Light Switch Cover

A triple-gang switch cover plate covering every practical combination of decora/rocker cutouts and blank panels, useful for setups where not all three gangs are wired to a switch. Each combination is available in a standard size and a slightly oversized "Large" version (+0.5cm on all sides, useful for paint buildup or slightly oversized wall openings). Most combinations also come in Version 1 (standard screw mounts) and Version 2 (exposed screw mounts removed on flat sections for a cleaner look), Triple Decora is the only style without a Version 2, since it has no flat section to clean up. The "end switch only" and "end blank only" files are designed symmetrically, flip the plate 180° after printing to get the mirrored version (e.g. the "left switch only" file becomes "right switch only" when flipped), so one file covers both mirrored cases. Designed in SolidWorks.
