This is a case to mount and to isolate mains voltage for the G3MB-202P SSR. There are two variants - a M3 and M2.5. Both variants use M3 hardware to mount the PCB and case lid, however the M2.5 variant has M2.5 holes to mount the case to extrusions.
Use 2x M3x6mm screws to hold down the PCB to the lower case, and a 2x M3x16mm screws to hold the lid down.
Suggest using standard Voron print settings.
