Hi mr_intensity,
First, I'd just like to recommend that, if you have any budget at all, that you pick up a different printer altogether. I believe that you will save more in time and sanity, and get printing more quickly if you do. I just bought a cheap chinese printer, and I have to say that it's amazing for the price.
Okay, back to your actual comments....
) OneUp broken/missing parts: You haven't said which parts. I originally bought a OneUp, and then upgraded it to a TwoUp. This means that there were parts that only fit the OneUp that were left over. I may have them somewhere, but I will need a while to search. If instead the parts are used on both OneUp and TwoUp, I have a second TwoUp that needs to be re-assembled (It wasn't put together quite well enough by its original owner). This means that I should be able to document any part from that machine, if that would interest you.
) Fixing OneUp droop: First thing is, I never had that problem - it depends on how lucky you get with the parts you have. If you want to fix the droop, you don't have to have the printed solution to the pulley system. In fact, I invented my own, using sliding door hardware from the hardware store (after my TwoUp got damaged and needed help). You can see a picture of this system on the fabric8r.com/site page. The main image cycles between three pictures. The middle one shows my TwoUp after I installed some printed upgrades. The pulleys are still on the machine, even though it doesn't need them with the upgrades. If you're interested in that, I can explain how I attached and adjusted the string/wire.
I'd also like to point out that I think it's likely that a fully 3D-printed printer is going to have quite a few design trade-offs that will make it less desirable in both assembly and use than it might seem from the drawings.
Having said all of that though, if you are interested in making and learning, then it will probably be quite rewarding to make your own. I have been happy with my One/TwoUp for that reason. But now I'm very happy to be moving forward with my new printer.
