🚨 FREE for limited time only Change log: Backpack was too large so we separated it into 3 parts. We added a mount bracket/lip so all parts can stay aligned while you are welding the parts after printing. We added a folded honey comb patterns so the backpack's creases can show correctly.

That Iron Man backpack looks super cool! The updates sound awesome. Gotta try printing it. I'm gonna check out royaledleΒ later, maybe find some inspiration. Fingers crossed it'll turn out great!
