Couldn't find a 3D modeled set of Decora wall plates anywhere online, so I made some based on widely available dimensions.
This print is a direct replacement for any Decora rocker, Decora outlet, or GFCI outlet cover (see dimensions pic). Great basis of design for making modifications to an outlet cover so it fits in constrained areas without cutting.
Both 1 and 2-gang plates are available in standard US or oversize (“Jumbo") dimensions. It is worth your time to measure your own outlet covers before printing replacements as although the switch and screw positioning is constant, the outer dimensions of your own outlet cover may vary. The .f3d files are available for download and constrained so you may simply adjust the sketch dimensions to fit your application while the screw and switch cutouts remain centered.
Be sure to flip the model over in slicer before printing.
I used PETG, but this print would benefit from PLA's extra stiffness.
