I've included a DIN rail mount if you need to mount it on a DIN rail. It has additional holes for mounting using M3 screws. I've included a STEP file in case you need to make modifications for your specific needs.
I recommend printing the DIN Rail mount with PETG. The SSR mount can be printed with PETG or other heat-resistant filaments.
