1/2 (half) Inch and 3/4 (three quarter) Inch Threaded Electrical Junction Box Plugs

thingiverse

This is a threaded plug designed for electrical junction boxes. Both 1/2-inch and 3/4-inch versions are available, along with models featuring a hex thumb screw that facilitates effortless tightening and loosening. I highly recommend using this type of plug due to its convenience - carrying around a large flat-head screwdriver just for plugging in is unnecessary. **Note:** It's advisable to apply dielectric grease to the threads to prevent water from entering your electrical box. Remember: To comply with the National Electrical Code, print this plug in flame-retardant filament and take steps to protect it from UV rays. This can be achieved by using UV-stable filament or applying a UV-protective coating.
