I have seen a few pretty good iPod docks made from knex, but they all seem to be pretty costly. However I only have a value tub on hand, so I made a strong, lightweight dock for all iPods. Plus, at only 24 pieces, its something most people can afford to do.
Step 1: Pieces
2 dark grey
Step 2: Base
pretty simple, follow the picture.
Step 3: Dock
make the two items, connect them as in picture 3.
Step 4: Assemble
snap the base into the open red slots. weave the cord through the assembly as in pic 2(sorry for the glare).done!
Step 5: Tips
pinch the two sides tightly onto the cord. when removing iPod, pinch plug so it doesn't come dislodged easily. adjust the tan connectors so your iPod rests comfortably on them.
