That looks really good, the quality of the print and quality of the plate are top notch!
I would rate print quality 10/10, but that made me zoom in and found a gap between two printed parts 😀 OP, it looks too good for that gap! Please fix that asap! Joking ofc, I think its amazing honestly…also dont even know how did you assemble that, but throwing this pic here just in case you want to know how I deal with alignement when gluing 2 parts 😉
It’s actually not secured yet. I included a couple of hexagonal openings in the long legs of the print that should accommodate a heated brass standoff just about right; it’ll be very similar to your alignment pins. I used the idea on my last keyboard and it worked well. The gap will be closed a bit more after securing the screws from the bottom plate. It will be nowhere near “perfect,” and but the end result should be a bit cleaner than this in-progress state. I am fairly pleased how decorative grooves draw the eye away from the seam a bit, but I’m not really trying to hide that it is 3D printed, and that in two pieces.
