| On the source-available piece: I'm not saying I'm for those over open source licenses in general, but Prusa brought up some fair questions when discussing the OCL. Essentially: define "personal use." Have I violated a non-commercial license if I print this keyboard and then use it to build someone a website? Does CC-NC mean a Prusacaster -- or any guitar knob with such a license for that matter -- is strictly barred from being taken on tour? Or used to record albums that are then sold? (And I say "guitar" knob, but I'm choosing an example a little consciously that could exist in any variety of controls, instrument and otherwise.) Where are the lines of that when it's physical things? How far downstream does that go if it isn't CC-NC-SA in particular? I'm not really sure that Creative Commons had the idea of physical production in mind, given that it dates back to a time when we were more broadly talking about digital piracy, and I honestly haven't kept up with its evolution much in more recent years. But maybe it just doesn't make the same sense for designs of physical things, for comparable reasons to why it wouldn't make sense for code -- and, conversely, open source projects that opt to use CC licenses for assets. (None of this would stop me from attempting to build/mod one for fun, mind you. It just raises what a more averse person might call risks, and what I will at least call curiosities.) |
The automotive aftermarket has largely settled that; even without the original design files, it's perfectly legal to make compatible parts, patents and the like notwithstanding. You can build an entire "small block Chevy" engine wholly from parts that GM did not make, and it will fit perfectly in a car that originally had the "genuine" one.
IANAL but as long as you don't violate any patents they have (if any) nor use their trademark, feel free to make and sell keyboards that look like theirs (not that a keyboard of their design is particularly distinctive anyway.)
