3D Printed Torsional Rubber Band Powered Car

This is a rubber band car for a school engineering project. The 3D files will require further machining in order to get the car running.

materials:

• 3D printer
• filament
• Lego axles, gears, stops, and holes
• hot glue
• drill
• Dremel
• 2 5x10x4 mm bearings

Step 1: Print

print off these three files

Step 2: (Not Required)

drill out all holes. 4 holes on either ends put legos holes over for more precise clearance
