The underside is showing the exposed PCB.
When designing the frame, I got inpired by the Falcon 8 macropad from MAX keyboard.
After the build was completed, I only has the black keycap set.
Roccat BespokeFX
I stared with a Roccat SuoraFX. I was never really happy with the board, especially the deck-flex was atrocious but I also didn't like the TTC Brown as they where quite unreliable.
I then decided to spend way to much money on modifying it, instead of starting from scratch. To start of, I got a bespoke stainless steel frame that I designed and got manufactured at HSL Lasertechnik.
I replaced the TTC Brown with Gateron Brown switches and got a couple of translucent PBT double-shot key-cap sets from AliExpress and combined them to one.
The layout is a QWERTY ISO-German layout with English legends. A bit unconventional, like the rest of the build.
