Recently, someone posted an instructables on how to 3D print your own pair of roller blades. But, having an entirely separate set of roller blades is rather clunky. If you have access to a 3D printer, why not take it a step further, and craft roller blades that simply clip on to your shoes? Imagine being able to pull them out of your backpack, clip them on, and rocket off!
If you try this, we'd love to hear about it!
