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 shelves stocked with all manner of vehicles – buggies, touring cars, prototypes – but you don’t 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 printer 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 for a spin this weekend. We’d love to see it take on the water with some 3D printed tyres, too.

  1. huh i had an rc car project that turned out to be not very fun because i needed to gear the motors down…despite using some 3d printed parts, i didn’t try to 3d print a reduction gearbox because i assumed it wouldn’t work very well at that size. but i guess it’s worth a try, if these guys managed to get it to work

      1. They can actually last a surprisingly long time. The trick is to keep them cool. Heat absolutely destroys PLA gears. I wonder what if he had a oil sump in his gearbox to keep them cool.

    1. Given the speed the car is running at, and the mass, I’d think that that aerofoils/wings etc would need to be quite large to have any impact on the handling. Also, how would the positive impact on the handling (downforce?) compare to the undesired drag due to the open frame & wheels (fairly low I’ think, given drag is proportional to v^2).
      Nothing wrong with a massive wing for purely cosmetic reasons though!
