I bought a Shop Fox W2005 Table Saw Fence with Classic Rails to upgrade my Craftsman 113 table saw. The fence didn't come with a mounting bracket for any kind of on/off safety paddle switch. After purchasing a Powertec Paddle Switch (71754), I modeled up a mounting bracket using the hardware that came with the fence and modeled one off the metal replacement bracket found on the Grizzly/Shop Fox website.
Its mounted to the rail with the two 10-24 x ¾ inch screws with a washer and a nut (provided with the fence). The paddle switch is mounted to the bracket with #8x32 machine screws with a washer and nut.
I printed it with 20% Gyroid infill in PETG (photos) and it has plenty of strength to withstand the forces on the bracket. I also printed it in PLA+ with the same infill and percentage and it was just a strong. Material choice will probably depends on how hot your garage gets.
