Solid state relay protector

I have designed a protective cover for a solid state relay that I have mounted on a personally designed printer, since the voltage on two of its terminals is 230V to avoid unwanted contacts.

He diseñado una tapa protectora para un rele de estado sólido que he montado en una impresora de diseño personal, ya que la tensión en dos de sus bornes es de 230V para evitar contactos indeseados.
