About this 3D model

Here's a pendant or a nice keychain that can change shape! Why opt for a static wearable or accessory when you can haveS one you and your special friends can play with... There's something magical about expandable structures that makes people go ''WOW''! Just push and pull from the sides and watch it transform, it's mesmerizing! But what's even more special and only possible with 3D printing is pre-assembled mechanisms like this one.
