I am planning attaching the extrusions to each other in the corners instead of relying on plastic parts to hold them together. I would use Mcmaster part number 47065T155 and then surround each corner with a printe part for the look. Do you think this would have the same kind of problems as just having printed corners?

Its not going to work very well. thats why the latest revisions are not hbot. i was building the hbot folda2 on my own as he posted the files and all the different versions. .
the plastic corner brackets make it flimsy and the y axis sliders do not have near enough rigity and to much flex. also over constrained so they just flex .
Bearing wise? I had the same problem. 8mm rods and bearings flexed too much.
My answer was, stop messing around with plastic parts and cheapo stuff. I made all aluminum parts and Im using 15mm rails and carriage proper. I made my frame super rigid, put DOWEL PINS! EVERYWHERE!
