Step 13:

Insert a pencil (round, not one with flat edges) into a wheel and push the axle assembly through one of the axle holes.
nice instructable, but remember, its how to print and assemble your car, not the basics of using a 3d printer
Very good i like the 3D Printer
Great Instructable! I like the simple, snap-togehter design. It could go much further if the rubberband wasn't tied around the axel - it looks like the car will unwind as it moves forward, then wind itself back up and reverse direction. Regardless, you have my vote for the make it real contest!
Thanks! You're correct--if you don't tie the rubber band to the axle (just hold it with your fingers while you start the wind), it will not pull the reverse trick you mentioned. Actually, I built a &quot;life size&quot; cardboard car using six giant &quot;pallet&quot; bands--and we had the &quot;wind it up; release; go past the starting point and return syndrome.&quot; Much more pronounced with little kids than 250 pounders. My wife and I gave rides in the giant car at the 2007 Austin Maker Faire.<br> <a href="http://www.youtube.com/watch?v=lVjAKWGvIj8" rel="nofollow">http://www.youtube.com/watch?v=lVjAKWGvIj8</a>
