Build 3D Printed Rock Crawler

Participants will assemble a 3D printed RC rock crawler, understanding its unique mechanics for off-road performance, and test it on a unique rock crawling course located at the historic ENCI Business Complex.

Overall Goal

To guide participants through the assembly of a 1/24 scale 3D printed RC rock crawler, focusing on the principles of suspension articulation, weight distribution, and high-torque drivetrains necessary for navigating challenging terrain.

Skills Used/Developed

• Detailed mechanical assembly (multi-link suspension, portal axles if applicable)
• Understanding of crawler-specific electronics (high-torque motors, specialized ESCs)
• Problem-solving for complex assemblies
• Fine motor skills
• Understanding of vehicle dynamics: center of gravity, articulation, approach/departure angles
• Strategic thinking for navigating obstacle courses

Tools Used

• Screwdriver set (various sizes, Phillips & hex)
• Pliers (needle-nose)
• 3D printed crawler parts kit (chassis, links, axle housings, etc.)
• RC electronics (high-torque motor, crawler ESC, steering servo, battery, charger)
• RC Transmitter & Receiver
• Weights for tuning (optional, provided)
• Safety glasses
