Desktop 3D printing is an incredible technology to be sure, but it’s not a cure-all. If you’re interested in making something in large numbers, or if production speed is a concern, 3D printing probably isn’t what you’re looking for. But on the flip side, if you want to make a few highly specialized or customized objects, desktop 3D printing represents an absolute revolution in capability for the individual hacker and maker.
In our ongoing mission to prove that desktop 3D printing isn’t just a novelty, we keep a close eye out for printable objects which play to the strengths of the technology. You won’t find any benchmarks or dust collectors here; everything featured in Printed It is a bona fide practical object. An ideal entry into this series is something that you wouldn’t need to print more than a few times, isn’t easily sourced or made via traditional means, and if possible, offers some form of customization which makes it more suitable to the individual’s needs than what’s commercially available.
Not every object we feature hits all of these marks, but this parametric hex key holder designed by [Daniel Leitner] absolutely does. This object was created to address a problem that we imagine most Hackaday readers share: taming an ever-growing collection of hex keys. What’s more, this design is something of an open source success story. It’s an idea that passed through the hands of multiple community members, becoming more refined and functional as it went. Even if you don’t personally need to wrangle some unruly hex keys, this object is a fascinating look at how 3D printing and the community that has sprouted up around it is truly evolving the process of going from concept to execution.
