My OneUp came with the NoelJean Gantry replacement, and I am sure they are better than stock, but still didn't support the right side as well as I would have liked. I found a different set on thingiverse that are working a lot better for me: https://www.thingiverse.com/thing:1447404. They hold the horizontal rods much tighter than the NoelJean pieces as they have the benefit of nuts/bolts in addition to fit to keep everything really tight. My X-gantry is rock solid now. The Noel Jean pieces do work with direct drive btw if you do decide to go that route. I have run across your build log! It was a good reference when I first got my OneUp. I got mine off ebay for something to do, it's been fun and has gotten me up to speed on all thing 3d printing but man has it been a basket case to keep going. I did get an Ender 3 a few weeks ago and it comes with its own learning curve, ex. Anything will stick to the heated glass bed on OneUp but not so much on the Ender 3. I still have hope for the OneUp to work alongside it, one day.
I have come across the z-rod braces but have not printed them out to see how they work yet. I didn't really like how they had to mount on the bottom but if they help the sway then it might be worthwhile.
At this point the only MDF I have left is the base and that's great. I recommend printing out the Y-drive and replacing that while you are at it. The bearing bolts actually thread into MDF
