A buddy of mine recently got a soft top for his Jeep. Thought I'd make a present for him. Not derived from, but inspired by la FabShop Mobile (https://www.thingiverse.com/thing:359008) and Tiny Toy Dump Truck (http://www.thingiverse.com/thing:9710). It took several tries to get an acceptable print. 4th time was the charm. The fill panels make it non-manifold, intentionally: They keep the rollbars aligned during printing. Note that I had to increase the rendering limit on OpenSCAD 2013.01 to avoid errors. Note that the solid panels behind the seats were an oversight in the code when I printed the final version: That's corrected in the .scad and .stl files I uploaded.Print with exterior perimeters first for best results in breaking the wheels loose. Cut the rollbar stabilizing panels loose after printing.
