Which keys are being used here, is it MX?

[MagedEWilliam]

Noob here,
After i printed the model here, i had trouble inserting the key switches, then it dawned on me that i might have printed the wrong model or that i needed to build it with the MX type that i have.

My question is which key switch are being used here, and how do i get an STL with my switch type.

Edit: found the key switch type, probably Gateron style switches
