RC Rally Chassis: MF-01RA

thingiverse

This RC Rally Chassis is fully functional and ready for personalized electronics. Although some parts, like screws, differentials, suspension, CVD cardan drive shafts, ball bearings, pinion gear, middle drive shaft, push rod, and motor mount are not printable, they can be easily purchased. The chassis plate is divided into three sections for printability, but it's strengthened with 4mm threaded rods and aluminum bars. For added durability, the bottom of the chassis has a 0.5mm aluminum reinforcement that can be cut by hand and glued in place. The motor mount is also glued to the chassis for stability. Printing with 100% fill makes this project pricey but still cheaper than constant replacement parts. A quirk of the upper suspension arms is their thickness, which allows for printing corrections and metal tubes for added strength. Finally, replace the bumper with thick foam as it's not durable enough in its current form. Feel free to leave comments!
