Prusa MK2S, MK2.5, MK2.5S Z-Axis Reinforcement/Brace

With the introduction of the new Prusa MK3(S) frame, I wanted to make my MK2.5S similarly rigid, if not more so. There were a couple great options, such as this: https://www.thingiverse.com/thing:1656945 This design and others came with two issues. Firstly, they all required complete disassembly of the Y-axis. And secondly, even if I did use one of their designs, the setup wouldn't work with this Y-axis upgrade I'm planning to install: https://www.thingiverse.com/thing:2836470 This solves both problems by being a drop-in solution; no Y-axis disassembly required. And it really does make the entire frame stiffer. Other than the printed parts you will need: Two 14.5" lengths of 5/16" threaded rod Eight 5/16" nuts Six 5/16" washers Four M3x20 screws Four M3 nuts Optional: Plastic tubing with 5/16" ID Print instructionsI personally used the following settings: PETG, 5 perimeters, 20% cubic infill, and 0.2mm layer height. You can use any filament, as long as it's fairly stiff after printing. I had some Proto Pasta CFPLA in my bin, but that seemed a little overkill at the time.
