Ender 5 Y endstop

My ender 5 kept hitting the carriages against the far x rail when I tried to set the bed size to 235 x 235 in Marlin.

I found that the Y carriage was about 4mm short of the silver corner brackets on the far side when it hit the Y endstop. When I tried to bring it to the "0" location on the near side it would hit the silver corner bracket after about 231mm meaning that I could almost reach the full 235mm by claiming the 4mm at the back.

The problem is that the stock Y endstop would not allow adjustment so I designed this one that does. I now am able to claim almost the full 235 volume but I left a few mm off for safety.
