The 552 looks like a standard tkl. These are like $16 and should fit:
104 Keys ABS Keycaps Cherry MX Blue Switches Key Caps with Keycaps Puller for DIY Mechanical Keyboard (Black Blue) https://www.amazon.com/dp/B07WKHTWLS/ref=cm_sw_r_cp_api_i_.c5cFbSFPA5VW
So I was at a local tech goodwill and found this keypad on a shelf with a $15(!) price tag on it. I immediately looked it up to find that it was a Genovation CP24. It was missing the customizable keycaps, but the cable and one long blue key was still there amazingly, so I bought it. I personally don’t like the feel of Cherry Black switches, so I swapped them for some Gateron Blue switches that I got from my buddies’ last build for a twenty. Keeping with the theme, I picked up a cheap set of teal keycaps on Amazon for $17 and got this result!
So in total:
Genovation CP24- $15 (used)
Gateron Blue switches- $20 (used)
Amazon keycaps– $17 (new)
Honestly I’m very happy with it! Definitely not a bad first build, but definitely way more challenging than I thought it was going to be.
