Step 3Get some magnets
I found K&J magnetics through Google:
http://www.kjmagnetics.com/
They have a huge selection, and I settled on their D32 3/16" disc magnets, which are 3/16" tall.

I got a pack of 100, and a pack of 25. I needed 108 for the cube prototype. If I build another, I'm going to beef up 12 of the magnets - the 6 pairs that form the axles off the center cube, probably to twice the width, perhaps to the D63:

They usually send free samples of different magnet types when you order from them.

Just wondering: It says "Free Samples" on the packet. I've looked all over the K&J site and can't find any info about free stuff. Do you have to be a customer to get free samples?
