Parametric Ethernet Plug Cap (Dust Cap)

An SCAD design (my first!) for generating ethernet plug caps; a dust-cap for ethernet switches. The caps fits a **female** socket.
It has several parameters:
```
// Switch properties
plug_spacing = 4.2; // Standard ethernet port spacing
num_plugs = 8;

// My switch consists of 2 modules of 4 ports each.
// There is therefore an additional space between each module
module_padding_every = 4;
padding_module = 4;

// Cover properties
thickness = 1.5;
padding_top = 10;
padding_bottom = 7;
padding_left = 7;
padding_right = 7;
```

A finished STL file is included, generated with the above parameters (as pictured).
