This bracket is better than the one that came with my Ender-2. The original one had the holes for the end stop switch too far in, resulting in x axis going too far to the left. The nozzle would be able to travel outside the bed, which is not good. This bracket has the end stop switch holes shifted a bit to the right, making the nozzle stopping over the bed.
See photo of original bracket holes compared with this new design.
Maybe this part is universal and fits ender-3 / other printers as well? Let me know.
I printed this with PLA, but maybe PETG would be a better choice.
