My office chair's pneumatic lift wouldn't stay up anymore, so I over-engineered a print-in-place support brace for it. The tolerances for the hinges are 0.3mm, so watch your slicer settings (especially if scaling). I was going to print at 0.2mm but it looked the like top hinge would fuse, so I dropped it to 0.15 and it was fine. After removing the supports it rotated very cleanly. I would recommend adding a zip-tie around the top of it to help it's rigidity.
Scaling the width shouldn't be much of a problem with anything as long as you go bigger (smaller will shrink the hinge pin gap tolerance also). Without scaling the height, it could be a few inches shorter by either/or moving it down through the z-axis plane or telling your slicer to stop printing a few lines short. If you go too much, you'll start cutting into the hinge.
I've added a picture in Simplify3D with automatic supports enabled. That's what I used and it worked well.
