move the lever mount spacer out of the panels, into separate part

this has two effects:

1. thinner and thicker spacers could be printed to accommodate
   preferences without having to reprint panels
2. I'm still testing this a bit, but by not having the spacer and panel
   be the same (partially hollow) part, I think the lever clickiness is
   a bit more pleasing to the ear

the second point is entirely arbitrary, so the first point is the real
benefit, despite me trying this because of the second
