Custom replacement case for the RK61, also fits Krux Neo Pro.

I wanted to take the stock RK61 PCB and put it into something that feels less like a generic keyboard case and more like a small retro console accessory — PS1 was the main inspiration here.

Went for that classic PS1 vibe in the proportions and overall shape, but still kept it usable as an everyday keyboard instead of just a novelty piece.

What this is:

• Drop-in replacement case for RK61 PCB
• Also compatible with Krux Neo Pro
• PS1-inspired retro design (boxy, clean, nostalgic look)
• Fully 3D printable
• Built as a simple case swap, not a full redesign

Notes:

It’s meant to be a straightforward shell replacement, not a complete keyboard rebuild. Depending on RK61 revision, you might need minor fitting tweaks (there are a few variants floating around).
