HI all ive bin looking at a few plastic board templates and wanted to know if sone
one has seen an effective looking plastic board
trukk, broad side suit and wave serpant

Its a web thing.. but I think what your looking for is generally called papercraft. (rather than giving you a fish I'm teaching you how to fish, get me?)
I can't remember quite how naughty it is and how much GW smacks people upside their head for trying to knock off their goods..so until I remember or a mod tells me off here is a link. (near bottom of page for broadside and trukk)

But dude.. you don't want to try making a papercraft eldar anything..fluid shapes out of cardboard boxes= 5 years work for something that looks crappy even if your moderate to ok skilled..I'd rather use the make a space marine origami template than try any eldar ship ones.

Or if it's just ideas for designs you are after, do some searches for "scratch built" versions of the things you want.

e.g. search for:
