Knex USB/ Wall Outlet Charging Station




About: I've been building and engineering since as far back as I can remember. My first building toys were those wooden blocks, and at age 4, I upgraded to cereal box samples of K'nex. I also participate in sports,...

Don't forget to vote for this in the USB contest!

I saw something like this online one day. It seemed like a brilliant idea, but I wasn't going to spend money on something I could make my self. This system allows you to suspend your USB charged or wall outlet charged device from the USB cord or charger. It allows for a tidier work space, or more surface area to place more clutter. The choice is yours! 

*A little disclaimer* : I am not responsible for any damage done to any devices due to a failure of this system (or any damage to your device really). If you don't believe this system will hold up your device then don't use it. My Kin 2m has yet to have a problem with this system, though. 

Step 1: Parts List!

The Total Cost for all of these parts is: (if ordered from K'nex's website) $4.57 (there is a minimum order of 5$ though, so throw some extra parts in there!, like green rods, they are easy to lose...) 
The cost of a comparable system is: $4 to $6.99, not including shipping and tax. 

K'nex is a more intelligent option due to the fact that if a knex piece breaks, it can be replaced without replacing the whole system, where as a solid structure that breaks must be re-purchased in its entirety. Also various things can be built with K'nex, and well, nothing can be built with the comparable solid structure. 

Red/ Green (metallic) : 2
Yellow/ Gray (metallic) : 3 
Blue/ Blue (metallic) : 4
White/ Silver (metallic) : 6
Green/ Black (metallic) :3

Blue 3D 7 way connector : 2
Green 4 way connector : 4
Red 3 way connector : 6
Grey 1 way connector : 2

1 #64 rubber band is also used in this, however any rubber band will work. 

Step 2: Build the Base!

Build what you see in the picture. 

Step 3: Build the Other Part That Goes Against the Wall!

No real name for it... just build it! fairly simple for most K'nexers, but I broke it down into steps for the less experienced/ people who never have built with K'nex before. 

Step 4: Final Assembly

Attach the two parts as shown. Then you are finished. Before use, ensure that your outlet / USB port / charger will hold up the weight by giving a slight tug on the system before placing your device on it.

    Looks like an excellent idea. I'll try it out next time I have to charge something!

    Thank you sir! It works with my DS Lite, so I don't know how much bigger the 3DS is... you might need to do a little modification...

    Yea... they've been lighting up that recent section when you click on the "you" tab... lol... I'm wicked low on parts... other wise I'd be trying a couple of them out... I'm currently trying to finish the UKP v2... I've got the whole thing down to a science, except for the trigger guard... I think I'm gonna put a picture up of it without it and update it later when I figure one out...
