Here is a model of a vintage bulldozer which I used to practice with Tinkercad. (It is the second version, but the first version was more toyish and is only published on Thingiverse) There is a detailed engine (printed in place), hard to see through engine cowling, but it is there, including cooler, 4 cylinders and pipes to exhaust and air filter. The model features a tool box with some tools (hammer, grease gun, nut and oil bottle) on the right fender, and afuel tank on left fender like some original old dozers are designed. The undercarriage has 3 (fake) support rollers on each sideThe general design is related to small vintage bulldozers like the Caterpillar model 2, the case 310 bulldozers or the Oliver cletrac oc3 and some toy bulldozers inspired from these good old machines) For source pls. see: http://www.2tontractor.net/ or http://cletrac.org/pages/model/pic-HG.htmlWheelbase is 60mm. Maybe it can be scaled, but I did not try myself.This was designed from scratch with tinkercad. Can be printed without supports. Try it, it'll work! You need glue (superglue) and some 3mm diameter rod, e.g. wooden or carbon or whatsoever. Front axle is 55mm, rear axle 62mm long.Print all parts in the desired colors, assembly is easy (see post printing instructions).Print in PLA except of course the tracks and -for easy assembly- the axle end-caps, which have to be printed in TPU (the rubber-like material).
