I wanted to make a quad in N scale (1/160) for a long time, but it took me a long time to find the right material thicknesses. This model is very tiny but actually looks like the prototype, all thanks to the wonders of 3D printing. I can not believe something like this can be mass produced fully assembled by conventional means. <a href="http://shpws.me/LyeC" target="_blank"></a>
