well this threads been helpful lol ive read a lot about ppl saying not to start on helmet, but on smaller simplier parts, but like kelevra16 said it was just too awesome to ignore. im doing odst halo 3 helmet and i already messed up with the scaling and had to reprint all the pieces, a while back i realised i accidently skipped a very small piece near the bottom and it took a lot of work trying to fix it, i fixed it (barely) but it set me back with all the time i spent trying to get the pieces alligned and to their proper shape, turned out that small piece missing warped that side and i didnt notice till i was done with the other side now ive got sunburn from da beach so im so far behind on my helmet project, but BY THE POWA OF GREYSKULL!!!!! i will get it done ^.^ i guess no matter what, dont give up because in the end (that so, very, far away end) your hard work will pay off.
