3 pin plug cover

thingiverse

When creating a 3pin plug cover, printing with strong filament is essential to prevent the pins from snapping. I opted for PETG, but make sure any filament you choose isn't electrically conductive. After printing, sand the prongs to smooth out any rough edges or burrs. Plug and wall sock covers can be tricky to push into sockets; avoid forcing it if it won't go all the way in.
