Built 2 versions of the MX/KS hybrid zilpzalp, here's aome height comparison when using bottom plates. It may be possible to use shorter stand-offs, but going 1mm shorter, stuff started touching the bottom plate so i left it like this.
Very nice! I’ve been eyeing the KS-33 switches for my next build and this is an informative comparison. To be sure I have it clear in my head: basically any MX compatible keycap works right?
I should have really added this to the OP! So actually, it depends on whether you use the switch plate. With it, compatibility is pretty poor, i.e. most caps will hit the plate.
DES actually even interferes with the switch itself, not the plate, making it uniquely unfitting.
I'm planning to get myself some skirtless caps for this plated built, or maybe i'll desolder and remove the switch plate...
