Intro: Thousand-Year-Old Egg Car
In the spirit of easter, delicious chinese food, and poor Frodo who really could have used a lift for the greater part of his unexpected journey, I present to you, the Thousand-Year Egg Car!
Things you will need:
- 3d printer (I used a printrbot simple metal with a heated bed)
- Exacto Knife
- STL files (attached)
Step 1: Print the Parts!
- Download the stl files and print them on your 3d printer.
- I used PLA.
- I recommend doing a test on the small wheel first. I had adjust my temperature and layer height settings slightly to make the wheels and car body print well. I ended up printing at 215C with a layer height of 0.15mm -- but do the test first, because the standard 210C may work fine for you.
- For the egg car body, I cut off 1 mm from the base of the geometry for easier printing. I also used support material.
- Use the exacto knife to trim off any unwanted whiskers and support material.
Side note: I tried to sand the surface of my first car iteration, however it turns the plastic a dusty white color and is a very slow and laborious process. So don't do that unless you intend to have that kind of surface finish.
Step 2: Attach the Wheels!
Back (LARGE) Wheels:
- Take 1 toothpick.
- Cut off the pointy ends of the toothpick with the exacto. The remaining length of toothpick should be at least 1-3/8" long.
- Push the toothpick into the center hole of one of the large wheels.
- Slide toothpick (with the wheel attached) through the holes in back of the car.
- Push the second large wheel on to the other end of the toothpick
- Adjust wheel placement on toothpick axles as necessary.
Front (small) Wheel:
- Take 1 toothpick.
- DO NOT CUT OFF THE POINTY ENDS!
- Place the small wheel in the gap at the front of the car. Try to align wheel hole to the axle holes in the car body.
- Push the toothpick through the first axle hole, then the wheel hole, all the way through the second axle hole.
- When the toothpick is firmly in place, trim off the excess length of toothpick with an exacto knife. I found it easiest to score the toothpick with the exacto and just break off the excess with my fingers.
