This thing is freaking AWESOME!!!!! It printed great, very easy and pretty dang fast. I assembled mine using a hot glue gun and it seems rigid.
I used MrCrankyface's drive-terrain and a chopped remix of his frame plus a center extension I designed. I used NEO72's body mounts on the cab and just bolted and glued the bed directly to the frame.
This thing is wicked cool, print it, its fun.
22 inches long, 8.75 inches wide, and 10 inches tall (dimensions may vary depending or your build)
Update: The body and frame were too heavy for MrCrankyface's drive-train, so I swapped it all out with metal. Other than that it is all 3D printed.
