Replaces Leviton 27 Wall Plate (US plugs, electrical). This has a smaller neck (distance between plugs) of 9.334 mm than other wall plates in order to fit perfectly. Pictured plug is using a blue-based glow-in-the-dark filament. In the future, I'll order a white-based glow-in-the-dark filament and replace all the wall plates and switches - should be awesome. VERY IMPORTANT NOTE: I read that most wall plates have fire suppression additives, even if they don't have a 'UL' certification (most don't). 3d printer filaments usually do not have fire suppression additives. (However, Home Depot and others sell even wood plates which obviously don't have fire suppression). Just be aware, in case there is any fire risk, such as an overloaded outlet or short, you would want to consider a different option.

I strongly suspect that a higher Infill, or a thicker front would provide a greater glow.Post-PrintingFace pattern is due to baseplate tape. Kepton tape would make it look smooth. glow in the dark
