Ok the final update,
First I decided to use one complete foam piece and make the cut outs for the steelbook and Artbook which are on top of each other, also added a little lip on the side of each of them to help remove them.
The same profile for the headset was used as the small foam holder in the previous update.
Lastly as requested by twisted I have added a numbered plate, though this was the best place to put it and not on the outside.
I decided to make the outer box with a a picture of a planet and a simple logo, the reason for this is that you can use the box as a cardboard canvas print because Mass Effect prints seem to be very popular prints.
I had actually done quite a bit of modelling for a military style case instead of a standard cardboard box but decided against it.
I guess that's it, any recommendation or alterations, I don't care how crazy it is. Would like to try and see what it looks like.
Also is anyone willing to write up the e-mail we are going to submit, I don't mind doing it but I'm sure there are better letter writers out there.
