perfect big wheels

I'm loving the new lock feature (now I've figured out what it does lol).
I used it in combination with orthographic mode to make these wheels.

The feature, if you've not tried it, is the little pad lock icon. Click it and it locks the item in place while building, in the same way as attatching to a platform. Select another item and click the lock icon and you can now force the two items together.
Its a great building aid.

Hope you like it.

Feel free to use these wheels, just give me a mention. :)
