To be fair, the blurb never mentioned that it was a test-fit project, and it's been more rare that people actually go to read the full article. (who can blame them with the clickbait ads at the bottom becoming full-on NSFW lately)
Also, the "Engineer in Training" title is just an internal forum title based on the number of posts, I'm pretty sure Wolfie hasn't taken the FE. (No offence meant, of course)

It would be very cool to print this in PTFE and run it with steam though.
