3D model description

I have designed this RC car in SolidWorks, and most of its parts are 3D printed in PLA. This one has similar dimensions to a 1/10th scale RC car.

Technical Specifications:

3100kv 3650 BLDC motor
12kg servo motor
Independent front suspension and Ackerman steering mechanism.
76:3 ratio belt-pulley mechanism for increased torque and concentric axis rear suspension mechanism which allows the motor to be mounted on the main body.
Torque is increased with double-sided helical gears. (38:6 ratio)
This car is completely made of 3D printed materials except for the driving pulley, shocks, motor, servo, wheels, and belt.

Driving pulley: HTD 2 10 teeth,
Driving belt: HTD 2,
Shocks: 1/10 RC Buggy shocks,
Motor: GOOLRC 3100kv 3650mm BLDC,
Servo: MG996r 12kg Servo,
Wheels: 1/10 RC Buggy Wheels,

And you will need some M3 bolt/nuts, a 30 cm M4 threaded rod, and some M4 nuts. All the dimensions for the bolts are available in the SolidWorks assembly.

You will also need brass tubes of various lengths. All the brass tubes have a 3mm inner radius and a 4mm outer radius. You can buy them and cut them to the required lengths.

NOTE: Please download the "Auth v.6" for the upgraded suspension, gear designs, and steering mechanism.

3D printing settings

This car is fully 3D printed with PLA material. I have used 40% infill in all of the parts except the gear and the pulley. Gear and the pulley are printed with 70% infill. You should use the support material when the slicer tells you to do so. (My slicer software is CURA) If you have adhesion issues you can use rafts too.
