After cutting the ring in half I cleaned it with chemical gasoline. Plain and simple, if you don’t clean away the fat (from your fingers) then the super glue won’t attach when gluing steel to steel. You won’t have this problem with epoxy or regular glue but as super glue dries so fast I went for that. It’s also completely transparent which is nice.
First glue the two rings and let them dry for 5 minutes and then mount the hinges. They need to be aligned so that the inside of the flipping part is aligned with the outside of the lid. It’s not clearly visible on the picture but you get the idea.

If everything is properly aligned then you will have this. You should fix the lid into place with two screws before start gluing the hinges on the outside.
This will ensure that it’s completely centred when finished.

As we want to make this hard drive look real when finished we need to have some fake screws. Well, what is better then using the original screws? I mounted them on a old hard drive and screwed them in a couple of turns. Then by holding the screw with a Torx screwdriver I cut the head off with the Dremel.
The screws should look like this when finished.

After gluing the screws into place I took two white stickers from another drive and mounted over the two holes in the centre. Then removing some old glue from a sticker with acetone and polishing it in general. And of course I painted the hinges on the outside using a black permanent marker. You see them if you look directly at them but most people won’t see it as it’s on the backside of the box.
And what hard drive is complete without the controller card? None, so I mounted that into place also.
