The original was too wide, the remix required supports, the cutoff was weak and bent upon Nebula cam weight. So I remade it into something that a more mechanically inclined person would do - modified the construction to have a supporting strut and removed the thick corner. While at it, I've also calibrated the camera to be higher and closer to the rail, just below the rail when pointed ~35 degrees down, to be overlooking the whole bed when starting, and have at least half the print visible even at the highest position. Also added a cable holder on the right.

Still not satisfied because the friction-based mount is too easy to move, but didn't find anything to latch it on. So when writing these lines, decided to make it at least more stable by the sheer size of the sides, and added a "_stable" variant that takes a bit more plastic, but hopefully provides better stability than the cutoff version.

[later edit] By now I've checked it and only recommend downloading the "_stable" version, which is indeed much more stable. So the older version is removed, and it is the only one left.

[even later edit] The version was updated with stronger USB cable holder that also has a bent tip to prevent the cable from sliding out.
