4wd, articulating and skid steering RC Car

thingiverse

This massive 4WD vehicle, nearly fully 3D printed, showcases incredible speed capabilities as seen in a video here: https://youtu.be/PbDKhWGhZAw. The Rhino file included allows for editing and personalization to your liking. Skid steering allows for agility at low speeds while articulation offers efficiency at higher speeds, thanks to a centre pinion system reminiscent of loader functionality. Check out this combination in action here: https://youtu.be/6YNzH0Ci6As. With independent suspension featuring motors within each oversized wheel hub and large "drifting" wheels, you can tackle diverse terrain. Printers with 12mm hexagon couplings like those from http://www.thingiverse.com/thing:1024399 or http://www.thingiverse.com/thing:470486 would also work. Note that for off-road excursions, rubber tires are the better choice but printed wheels shine on grass, sand, and other smooth surfaces. Observe how this version builds upon previous skid-steer only designs from Thingiverse like http://www.thingiverse.com/thing:1024399 with enhanced suspension, wheel carrier (motor mounts), making it more robust overall. Inspect the improved arrangement in this video: https://youtu.be/CsUW8GbgfBI Rubber tires have a remarkable towing capacity. However, if you fit smaller rubber wheels and ride on a skateboard, be prepared to tow along - albeit at a glacial pace! Print Settings: Printer Brand: UP! UP Plus2 Rafts: Yes Supports: Yes Resolution: 0.2mm Infill: Solid Notes: Actually utilized an UP! Box due to printing challenges with the Up! Plus 2. Witness the reinforced cage atop the front suspension towers in one photo, built using 6.3mm aluminum. Find a template for bending these bars within the .3dm file. Utilized crystal clear ABS for steering parts, as it has proven to be incredibly durable. To strengthen the vehicle even more, I employed an airgun set to 270C on stressed areas that are prone to cracking or joints, such as those where different components meet.
