It was easier/cheaper for me to find 400mm aluminum extrusions pre-cut online compared to the 410mm this original design was built to work with, so I extended each bracket by 5mm.
I imagine 450mm and 500mm pre-cut lengths will be similarly easier to source than 460mm and 510mm, so hopefully this remix is helpful for your printer setup too!
Thanks Tinyfluffs! :)
