3D Printed RC Truck V4

myminifactory

Where to even start on this project... This is the continuation of the 3D Printed Rc Truck V3.I remade 80% of the drivetrain and it's now a full-time 6x6 rock crawler. The whole idea is to make everything easily replaceable if it breaks and all the hardware you need is screws and bearings.Axles, "differentials", transfercase, driveshafts, wheels, chassis and so on is all 3D printed. I have done all my prints in PLA with ~50% infill and 4 perimeters. Holds up well.The axle shells could benefit from being printed in a more durable plastic, maybe copolyester.
