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

print off these three files

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

Drill out drive shaft hole to 10 mm, insert two 5x10x4 mm bearings.

use Lego axles, wheels, gears stops, and t brackets to complete drivetrain
