Liked the toy-type shape of this GWAA AFV a lot. This could be a nice toy, for my little boy (11 months now). Printed interfaces: I made a complete re-design, so you only have to print the plastic parts. (No need for screws, bearings, rubber tires etc.) Multi Purpose Vechilce: Although I could creat a tank, I better let him play with something more friendly. That's why the barrel could also be replaced by ladder or a crane. Size does matter: 4x4 or 6x6, both looking nice. Finally printed all parts. It's massive :) Due to some warping, you see some split marks, beside that my son kind a liked it I guess. EDIT 20180412: Increased inner diameter with 0.1 mm (wheel_03). It will run a little better. Also uploaded wheels with some profiles. EDIT 20180415: After discovering this nice MGS vehicle, I just needed to update this MPV to 8x8.
