Introduction: 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

Step 3: Bearings

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

Step 4: Drivetrain

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

Step 5: Add Body

    This is really cool. I love how you combined legos with 3D printed parts. You could even probably make the lego pattern on the 3D printed parts so that you can attach legos to the outside too.
