Heh, most such open source projects don't want to "go commercial", that's the exact point. And I'm not sure how RedHat is exactly "an open source project who went commercial" or rather a commercial company doing open source.

Yeah, not sure why this is getting upvoted. They are just having the standard open source 3D printing apps in the repos, nothing else :s

Yeah \o/ We first build an original Mendel at my Paris (France) hackerspace, then used it to print my own Prusa i1, which I upgraded to an i2 over time using itself, and printed a Prusa i2 for a friend with my i1. RepRap rocks :)

More than a tool, 3D printing is really a big hobby for me. It's not just about getting 3D objects printed, it's also about how the prints go, how the quality varies given the slicing/printing parameters, and how to push everything further with the community.
