Actually, i left that small gap there deliberately. If you look at the original version you'll notice that it doesn't connect to the back perfectly. There's a small "trench" going in between the pieces. It looks a bit strange at this stage, but i hope that it will look ok a little later on . Will be posting some new progress soon.

Magicsy, thanks a lot for the compliment but i'm not nearly as good as you. I saw your dyson vacuum and i find it to be incredible. Keep up the good work
