replica backpack

Has anyone scratch built a Clone trooper backpack like the ones in the clone wars tv series? I'm struggling with where to start.

So thought I'd share another build from start to finish in Depth, my last one being an Iron Bot replica from the Iron Man comics which you see here Iron Heart - Iron Bot Replica from Invincible Iron Man Issue 595. This time, with just over 2 weeks available before the Season 6 battle pass...
