Stackable router/modem rack

A rack sized to fit most residential routers and modems for those who wish to stack a router/modem atop another router/modem. The rack contains large air holes on the tray to prevent overheating. May also fit other mini PCs and devices (E.g Intel NUC, External Hard Drives).

Note: This design is an extension of my original design (http://www.thingiverse.com/thing:127094) for those who wish to stack more than 2 devices together and contains indentations to stack more racks on top of it. For those who prefer to complete the topmost rack with a non-indented rack, please use the original rack as the topmost rack.
