North American Outlet Plug

Outlet plug for Type B (NEMA 5-15) Plug/North American 3-pin plug.

I wanted an outlet plug that didn't make contact with the hot and neutral wires of the outlet, so that you shouldn't need to worry about the breakdown voltage of the material that you're using (probably not necessary, but makes me feel better, especially when my little one grabs one of these).

Print in the default orientation (grounding plug on the bottom) to minimize possibility of it breaking off in your outlet. Shouldn't need any supports.

Depending on your printer and your outlets, this can be _very_ snug, and may require the use of pliers to remove. Because of the design, this shouldn't break when removed with pliers (I've had to do this a couple of times). I see this as an added safety benefit -- if I you can't remove it, then your little ones shouldn't be able to either.
