Last week, [Danal Estes] passed away. This comes as a shock to many of us who had the pleasure of interacting with him online. Not only was [Danal] an active contributor to the 3D printing community, he was simply a warm-hearted character who was just fun to get along with. I met [Danal] online less than a year ago. But I owe him a debt in helping transform a set of design files that I posted online into a full blown community of hardware enthusiasts.

Here’s my best shot at recounting some of this fellow human’s legacy as seen from the fellow tool changing 3D printing enthusiasts who knew him.

Getting to Know an Online Community Builder

I first met [Danal] online last September through Thingiverse when he posted a make of Jubilee, a tool changing machine design that I posted a few weeks prior. At a time when Jubilee was just a set of files and instructions on the internet, I was stoked that someone in the world was out there building a duplicate. To get to know these people better and work out any pinch points in their assembly process, I started a Discord Chat Server. [Danal] was the first to join and start telling his story in pictures.

As a community of curious people on Discord grew, questions about the machine started to arise. How big was it? How did the tool changing work? I tried answering as many as I could, putting an FAQ blurb on Thingiverse, But a few weeks in, something else happened: [Danal] started answering the questions. Not only that, he was greeting nearly every single person who introduced themselves on the server. I didn’t understand the value of a simple “welcome aboard!” that follows someone’s first post in a budding online community, but [Danal] did. So he did just that. He made you feel welcome to have landed in this corner of the internet. In a world full of engineers who don’t like repeating themselves, [Danal] seemed to get that his repeat interaction was new for the person on the other end; and that made it worth doing.

As the days passed, questions continued, and [Danal] continued to fill people in with answers to questions–even repeat questions. All the while, he posted progress pictures of his own machine. In a way, the rest of the community seemed to be holding their breath during this time, watching [Danal] post status reports; waiting for some conviction that these files actually turned into something that worked. Then, less than a month later, [Danal] posted a video of his first successful tool change. It did work! Almost certainly inspired by [Danal’s] success, a few more folks started building machines of their own. But [Danal] was the first person to duplicate a Jubilee.

More than twenty machines have been built in the wild since I posted the project …read more
