I'm about to buy the pieces to build an ortholinear board (my first, both building & ortholinear), finalizing decisions and all. But the PCB I'm getting is all, well, linear. No possibility of having any keys off-center at all, it's designed 100% in straight rows of solely 1u spots. But I really want at the very least one 2u (or maybe 3u?) keycap for a space bar (or two). But in my experience, 2u caps come with the ...socket? in the middle where the switch is located off-center with a stabilizer, not made for fitting on top of two switches. Are there 2u & 3u keycaps that can fit properly over two & three switches? If so, please point me in the direction where I can find them? Thanks!
