Hey guys, in this instructable I will be showing you how to make a simple small 3d printed or cardboard version of NASA's helicopter, called Ingenuity, which recently made history on Mars as the first spacecraft to successfully fly with rotors as the method of propulsion. This project is great for all ages and lets you own a small piece of history!

Supplies

1. Toy helicopter: https://amzn.to/3xy7xeh

2. 3D Printer or Cardboard

3. 1/16" Diameter Brass Rod or something similar like toothpicks: https://amzn.to/3xyIEiL

4. Mylar Gold/Silver Film: https://amzn.to/3u7JUar

5. Spray Adhesive: https://amzn.to/3vq42F5

6. NASA Sticker: https://amzn.to/2QHLdhJ

7. Scissors for the film/cardboard

8. Snips for cutting the rod

9. Hot Glue

Step 1: Dissassemble Toy Helicopter

Use a small screwdriver to remove the 4 screws from the body of the toy.

Carefully remove the electronics and try not to put too much pressure on any of the thin wires.

Set aside until the body is ready for the final assembly.

Step 2: 3D Printing the Body and Feet

Step 3: ...or Make Cardboard Body

Print out the attached flat pattern on standard 8.5"x11" paper. Be sure to set the scale to 100% or it will not be correct. You can alway use a caliper to double check the dimensions called out on the page as the model is drawn at 1:1 scale.

Step 4: Apply Metallic Film and Attach Legs

This step is optional but if you want to use the film, simply cut a piece of film to 5"x5".

Use spray adhesive to coat the film and the body. Carefully begin scraping with a piece of cardboard to smooth the bubbles out.

Use scissors to trim excess film from the edges and fold any remaining film.

Puncture the film with the brass rods, cut to 3", and insert them into the body. If you are using the cardboard version, you will need to use hot glue on the inside to hold them in place. If you are using the 3d printed body and the legs are a little loose, just apply a small amount of glue on the ends of the rods and press them back in place.

Step 5: Final Assembly

If your body is covered with film, you will need to make a small slit along the opening of the body to get the electronics in.

Tuck everything neatly inside the body with the usb connector facing down. Use a small amount of hot glue on the inside to keep the electronics from ejecting during a crash.

Step 6: Off to Mars!

That's it! Now go build your own little fleet of Mars Helicopters!
