This is the first iteration (third internal) of my attempt to make printable Velcro. It is pretty nice to hang things, probably this small piece will resist much more than a kilogram of weight (hanging weight) and it is very easy to remove.3d printing revolution is just starting, I don't say this is a flawless piece but I really consider it is a very good example about a very sweet future about us modifying our brains from "search-buy-adapt" (frustration included) to "think-design-print" (self-pride included :D ).Quick demo video: http://www.youtube.com/watch?v=BtLSMI3xVDY Quick demo #2 (perpendicular): http://www.youtube.com/watch?v=eLehgIfjmpAThis was an object that did not exist in our 3d printing world, so I like to think this is an "upgrade" from real world to a better virtual&teleportable world ;)
