I finally managed to get the time yesterday to glue together the tester so here's a pic:

(As always apologies for the appalling quality of my phone's camera

)
The helm was very simple to put together and a nice warm up for the final thing.
I did have a bit of trouble getting it on at first but I trimmed the bottom a bit:

and it went on fine.
It was a bit big so I'll probably stick with the defauly 1/2 cm smaller proper helm.
I only noticed one fold which seemed to not be needed at all which was on the base of the jaw between tabs 27 and 101 although that might have gone in to seperate the two edge pieces (you can see it on the pic above on the far right in about the middle).
Anyways now that's done its on to the real thing, I've got the jaw printed out so will be trimming and scoring today before assembling piece by piece.
Thanks for the great models once again
