3-Prong Plug Cover

I wanted a cover for a three prong US plug, but I couldn't find one, so I designed this one.

Updated:
New models fit plugs with the two different sized prongs, and has three levels of protection
Low is a quicker print just to protect from dust and light damage during storage
Medium will protect from prongs bending from most impacts
High has extra reinforcement to protect every part of the plug and prevent bending or damage except under extreme forces
