This is a simple adapter plate to allow for wall mounting an Asus RT-AC66U router. There are two holes for countersunk screws (#6 size) which go into the wall, and the little square flanges engage with the holes in the back of the router. The semi circular cutouts are to allow ventilation. This was developed in 123D Design Online, and the editable file is here.The object as oriented is upside-down, so that the flanges can print without support (and aligned with the strongest dimension of the filament). To install, turn it around, so that the flat side is facing the wall and the two "legs" are pointing down. Put a #6 screw with a countersunk head in one of the screw holes and screw it in. Use a level to make sure the bracket is level, and then put in the second screw. Hang the router on the flanges and pull down to seat it. (Don't pull too hard!)
