I bought my ender 3 long time ago. the issue that I was facing is when I autohome, the bed will stop way after the nozzle. I tried to move the y-end stop but for some reason on my printer it was fixed !!
So I designed this part to replace the one that came with the printer.
What it does is to push the y limit switch few mm to the front effectively fixing the issue.
