This is a 3d printed design for an electrical plug cover as splash protection in a bathroom. Our plug is located too close to a sink which is not safe otherwise. The cover is fixed over the the plug with a small hinged unit, so that it can be lifted for electrical usage. The cover works well for our plug, but you can fork and modify my design directly on Onshape to fit your plug if it has different dimensions:
