This is a project to build a 3D printed remote controlled car. The car body is based on the Cybertruck from Tesla. The car is designed to be 3D printed and to be controlled by a remote control.
The car uses off-the-shelf drivetrain components compatible with Traxxas Slash 4x4 parts:
- Differentials - Metal differentials with bearings
- Driveshafts - CVD steel driveshafts and metal center driveshaft
- Slipper Clutch - Complete metal slipper clutch assembly
- Drive Hubs - Steel drive hub sets
This makes the car durable and easy to repair with widely available RC car parts.

Depending on the print settings, you will need around 2KG of Filament to print all the parts. Instead of PLA, you can also use PETG or ABS.
For TPU parts (except tires), we recommend Extrudr Flex Hard for better impact absorption.
