Seeing as my mp44 ko snapped I thought I do a Frankenstein and start messing around with that backpack- admit-tingly I was growing use to it. So it’s the same idea front of truck rotates to back and forms the backpack. Bit hard to explain but this time I got the bumper to rather then fold on top I design it to rotate so it sits on the bottom.
Ignore the rough lines (draft print) Not sure about the gap between the back and backpack due the slant truck mode has. the back/grill will get covered up with same way with the official with the back of truck mode. Just need to design that next. pretty pleased with with side bumpers tucking in.
