The front section that houses the hinge pin was a pain.
I ended up doing it 3 times, the issue is merging shapes.
You have the lower door, the inner seal area, the gaurd profile to match the front clip.
You have to bring them all together and make them work.
I got it on the 3rd go at 4.30am sunday morning,yip I couldn't let it go.
Sorry about the quality of the photos Im still working of my Ipod.
