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.
