MatCat RC Car
This is the official repository for the MatCat RC Car, an RC car designed to be 3D printed. I designed this car primarily as an exercise to improve my modeling skills, but also because I wanted a cool RC car to play with! The RC car is designed to be an all-purpose RC vehicle, the initial model is a rear wheel drive double wishbone suspension vehicle designed primarily for 'on road' driving, though a 4wd model is planned as well. The car is completely designed from scratch for 3D printing, the only non-printed parts are metric screws, ball bearings, and electronics. The vehicle is roughly 1:7 scale based on vehicle width compared to average vehicle widths, this would make this vehicle roughly on par with a small compact vehicle in scale. Please note any and all specificaions are subject to change as this is a work in progress.
