No need to reprint existing parts; just leave it as is. There's no room for loss of printable space here - we're keeping things neat and tidy. We're going to tap into the PLA property to give our system that perfect elastic force. It's all about ease, after all. Installation shouldn't be a hassle, should it? I think I've got it working now... Let me show you! 01-09-2015 Update If you experience any wear on both the threaded rod and nut - especially if z-lift is your go-to method - then that's no biggie. It means you're getting some quality use out of your machine. You know when it's time for a Z step motor check: it skips steps and struggles to lift the Y carriage. Happened to me after 6 months, but then I swapped it out for a shiny new stainless threaded rod. The price tag? Ridiculous (2 EUR). The quality's far superior to the original though, so I'm not complaining. Make sure you upgrade those nuts too; no need to go overboard on torque either - that top nut should be easy going. Here are some snaps of what you can achieve with this handy add-on: You've got a quality control task ahead of you: check those clearances regularly, and tighten them if they start to get loose. If they're not secure, the whole operation's as good as nothing. It makes a huge difference, let me tell you - it eliminates all that Z-wobbling nonsense for good!
