Just got Autodesk Fusion 360 during their sale and to test it out I've been playing around with designing some autococker bodies. I'll just post whatever I come up with here. Nothing serious and I'm not 100% on the dimensions as I'm referencing material I find online and my crappy calipers
Here is one I did today. Its rendered in Autodesk Fusion using the in screen capture. Which imo does better then their raytracing. I'm a 3D artist professionally and It's pretty convenient to have such a simple render engine built in for quick stuff. Its not particularly accurate but it gets the ideas across really quick.
heres another random design I did
