To enhance my K40 lasercutter I used three Omron SSR found in my shack: https://www.aliexpress.com/item/BGEKTOTH5V-1-Channel-OMRON-SSR-High-Level-Solid-State-Relay-Module-250V-2A-For-Arduino/32878321772.html To be able to mount them fixed and isolated into the device I designed an extremely simple case. The four M3-screws at the corners can be used to only fix the cover or to mount the case when screwing through a wall inside the device. The PCB snaps to the stands and will be fixed by the cover.
