Nearly Entirely 3D Printed RC Car Is 4WD Fun
Remote control cars can be great fun, particularly if you've got a spare carpark or dirt lot to hoon them around. Any good hobby store will have stocked with all manner of vehicles - buggies, touring cars, prototypes - but you do not have to settle for what's already available. Why not 3D print the car of your dreams instead? (YouTube, embedded below.)
The build comes to us from [Engineering Nonsense], now in its third revision. The design is produced in PLA, to make it accessible as possible to printers owners the world over. Almost the entire car is 3D printable - not just the chassis. The gearbox, differentials and driveshafts, and even suspension arms and tie rods are all printed, rather than bought. This also means the car is easier to build, with everything being printed to the correct size, as opposed to using off-the-shelf adjustable parts.
Performance is impressive, with the car showing good grip thanks to its 4WD drivetrain and double wishbone suspension. Files are available on Thingiverse, so there's nothing to stop you from printing this out and going to spin this weekend. We'd love to see it take on the water with some 3D printed tires, too.
