Never worked as expected for me too. I’ve switched to voyager, working great there.

Very nice

Do what Foss do you suggest?

I think it has the smallest gaps between keys I ever seen

Congratulations, it’s amazing!

I like how you use low profile keys for first row in thumb clusters, and high for second row. I came up to same idea in my custom build. (But in really awkward way by gluing two keycaps together )

3. Don’t have this screws and have a bit different keycaps on my chocs, but most probably yes. My keycaps have 1.5mm gap from top plate. https://lemmy.world/pictrs/image/e22f231e-2e3b-4438-898e-508bf5dcf826.jpeg
