Easy-remove electrical outlet cover

Unlike those electrical outlet safety protectors that are made deliberately difficult to remove, this outlet cover is made easy to remove. It is intended for use in a covered outdoor patio, to keep out bugs and debris when nothing is plugged in.

This is designed for a NEMA 5-15R electrical receptacle, which is commonly used throughout North America, Japan, Taiwan, Ecuador, Columbia, and Venezuela.

I designed it for Decora-style receptacles but fits standard receptacles too. The photograph with the wood background is a standard wall outlet, the other pictures show Decora-style outlets.

Only the earth-ground pins are needed to hold this in place. The other pins are unnecessary, too thin to print 100% reliably, and require too much support.

**Update** 26 May 2024: Shortened ground pin by 5 mm to make it about the same length as the "live" flat pins would be. There's no need for this plastic pin to be as long as an actual grounding pin. A longer pin is more easily broken.
