People raised some interesting points about how "ugly" the solution was and then criggie suggested using magnets and we thought, hey, that's an awesome idea, so we tested it and loved it :)
Here is a simple Instructable on how you can make this too.
This is a smart idea that is a total pleasure to use, I imagine that you can have loads of quick access ports dotted around the back of your machine now, the possibilities are endless.
WHAT YOU NEED:
1. sugru - one mini pack is enough to make 3 of these
2. Neodymium magnets (we got these ones from ebay but you could probably use slightly smaller ones)
3. USB extension cable (male to female)
5. tissue paper
Step 1: OPPOSITES ATTRACT - Label Your Magnets
With magnets, OPPOSITES ATTRACT, this is the key thing to remember so we recommend that you label your magnets.
Allow your magnets to attract, (if you are using Neodymium then be careful, they are powerful)
Label the sides, we marked ours with plus and minus signs.
Step 2: Prepare the Magnets
1: Break the sugru into 3 equal pieces.
2: break one of these pieces in half.
3: shape these pieces into small cones.
4: Press the pointed end onto the sides of each magnet;
One piece onto the plus side of one magnet.
The other piece onto the minus side of the second magnet.
Step 3: Apply Magnet to Computer
Press the sugru that spreads out around the magnet to help ensure a strong bond.
Step 4: Apply Magnet to USB
Again press the sugru that spreads out in around the magnet.
Leave to cure overnight.
Step 5: Enjoy the Good Life
Now you have an easy to find USB extension that is kept out the way.
