Vintage bulldozer

myminifactory

Here's a model of a vintage bulldozer that I used to practice with Tinkercad. It's the second version, but the first one was more toyish and can only be found on Thingiverse. A detailed engine is built into this model, printed in place, making it hard to see through the engine cowling, but it's there, complete with a cooler, four cylinders, and pipes for exhaust and air filter. The model features a tool box with some tools - a hammer, grease gun, nut, and oil bottle - on the right fender, as well as a fuel tank on the left fender, just like some original old dozers are designed. The undercarriage has three fake support rollers on each side. The general design is inspired by small vintage bulldozers like the Caterpillar model 2, the Case 310 bulldozers, or the Oliver Cletrac OC3 and some toy bulldozers based on these classic machines. For source information, please visit http://www.2tontractor.net/ or http://cletrac.org/pages/model/pic-HG.html The wheelbase of this model is sixty millimeters. It might be possible to scale it, but I haven't tried that myself. This bulldozer was designed from scratch using Tinkercad. It can be printed without supports and works well if you glue the parts together with superglue and use some three-millimeter diameter rod - for example, wooden or carbon fiber. The front axle is fifty-five millimeters long, while the rear axle measures sixty-two millimeters. To assemble this model, simply print all the parts in your desired colors. Follow the post-printing instructions for easy assembly. Note: Print the tracks and axle end-caps in TPU (the rubber-like material) for a better fit and easier assembly.
