Anyone who has ever broken an arm or a leg knows full well how bulky and unwieldy conventional casts are. A group of engineers wanted to improve the experience and make casts more than just rigid structures to hold bones in place. The BoomCast is 3D printed based on a scan of a person’s leg and comes in two parts that snap together and can come apart as necessary. It has a sole like a shoe and there are sensors built-in that can track your walking. Plus, as the name implies, the BoomCast has a boombox built right in. It’s not clear why, but then why not?

Here’s a video about how the project came together and what the thinking was that led to the BoomCast:
