About this 3D model

As part of my home renovations, I need more electrical outlet cover plates. This thing covers nema 5-15 plugs. These are the standard "Duplex" electrical outlets found in most home in the US. The OpenScad has code to print up as many 'gangs' as you want. One Gang == one set of two plugs. A "Two Gang" would have a total of 4 plugs, "Three Gang" would have a total of 6 plugs, etc. This thing is not a strict derivative of, but similar to: http://www.thingiverse.com/thing:3342 It is also not a strict derivative, but additive to this thing: http://www.thingiverse.com/thing:6588 UPDATE: Spacing on the outlet sockets was slightly off
