(Image: MagSafe Adapter Key Ring by jbobrow) Have you seen the The Free Universal Construction Kit? It's a super-clever set of connectors that allow you to combine different types of toys. Like hook up your Lego to Fischertechnik. Needless to say, kids love it! http://www.shapeways.com/blog/archives/1267-the-free-univers al-construction-kit-3d-printing-interoperability-between-chi ldren.html What's interesting to me is that the individual manufacturers would never create these connectors. But as soon as you have access to a 3D printer, it's easy to make it yourself! Taking this one step further, I'm curious what other kinds of objects you would like to connect? The Magsafe Adapter Key Ring is one of my favorites (and its creator Jonathan Bobrow just finished a successful Kickstarter campaign with it, congrats!). Let's see what you guys can come up with during the weekend Enjoy! How to Enter Design something that connects two important things in your life. Post your work here on the forum, and add a picture! Deadline is Monday evening, midnight. What's the prize? $25 to use towards your creation, or any other Shapeways purchase. That's all? Certainly. Have fun!
