Interesting thing that I noticed while printing.
I would expect that the four horizontal hinges are positioned at the same Z height in the model. If they were at the same Z height, I would expect them to slice in exactly the same way.
However, it appears that the bottom left hinge is slightly lower than the other three. I don't know if this is done on purpose, but you may want to address it in your next revision.
Thanks for this great remix, though! I'm printing mine as we speak!
