This model is shaped specifically for my handle, which is a noname low-end one.
The 195mm size is however standardized (at least in Europe). Remix the model preserving the screw holes and front plate position, adjust the back for your handle.
The middle screw is the one from the handle. The 2 lateral screws are supplied with the metal backplate of the SwitchBot Lock. They need M3 nuts. I drilled 2 holes at the back of the device case to prevent the back screws to take additional space.
