So after printing on my modified tronxy, and printing a custom build plate attachment, I was able to take a 1$ pane of glass, and now thanks to this I have a 200x300x350 build volume :D
Side note, I LOVE the motor mount and pulley system.
Having the bearing horizontal makes setup so much easier..
SIde side note, after some trouble I opted to NOT use a spring, as my plate would always wobble with the spring...
But now it's firmly attached and I can always adjust it :)
I gave the parts 4 perimeters and it was printed with a 0.5mm nozzle.
