This
is the entire kit. Everything comes in a bag and it comes with a
copy of Ton's web page on How to make a 3x3x3 Speedcube.
Here
are all of the pieces layed out:
8 Corners
12 Edges
6 Centers
6 Center Caps
6 Springs
6 Big Metal Washers
6 Small Plastic Washers
6 Screws
6 Rivets
1 Axis

This is how to build-up the center-pieces. Do this six times.

Finished Axis. Note the arched centers. Next pop in all of the corners and edges.

All that needs to be done now is to glue on the center caps on and apply stickers. I recommend tuning and lubing at this point.
