I'm not sure if I did something wrong in my print, but the switch is completely missed by both X motor brackets (meaning switch mounted at front as well as at rear). The print can't work as your photo displays because the only side of this mount the switch screws make contact with has the switch pointed in the opposite direction from your photo.
Should I just re-print it in reverse of the standard STL layout?
Ignore the above. I removed the factory bolts and used M2 bolts and washers on the smaller hole back side. Then to ensure things didn't move or break loose, I added another 2 washers and a pair of nuts to the end of the 2, M2 bolts. Now everything fits and works just fine!
