How about signature plastics DSA/SA keycaps? They have a international kit, nearly always. Or is your ISO to ghetto for that as well?>>54120508
Are you implying, that thickness only matters with ABS? Because that's not how it works. Only differences between ABS and PBT is, that PBT is near impossible to Doubleshot and ABS looses its texture with time (how long depends on quality, not thickness)>>54120577
It really depends. Pic related was like
80$ for housing (which already acts as a switchplate) - GON skinny 60
60$ for PCB - GON 60% PCB, but you can get a 30$ SATAN GH60 PCB
10$ for stabilizers
~20$ for LEDs, but you don't need those, obviously
40$ for Switches
30$ for Lube, but cheaper stuff will work as well. I just wanted krytox since I'm planning to lube quite a lot of keyboards and 30$ aren't that much, when you can use it on 10+ boards.
So without any extras a custom kb would be about 220$+keycaps and soldering. That may seem a lot, but you also get way better quality than any stock keyboard has to offer, except for the whitefox maybe, but you're to late for that one.
