I really like the range of adjustment this bracket gave, but it was a little bendy in my situation, so I thought I'd try doubling the thickness of the center brace.

Other aspects remain the same.
I'm trying it at 80 percent infill, to see if this kills the issue I had, which was a slightly bouncy stepper mount, not ideal for micro z adjustments.

I also tried reducing the y length by 1mm, as it was possibly ever so slightly too tall for the OEM creality steppers.
