Endstop for Ender3 linear rails

thingiverse

I have my Ender3 equipped with linear rails. I noticed that these linear rails only work properly when they are mounted horizontally. Originally, the manufacturer intended to mount the two rails, which are used for the Y-axis, rotated by 90°. This does not work with these rails because the internal balls noticeably cramped and create a very large resistance. Oil / grease or clean with isopropanol has done no remedy here. So I have a Mount on which the rails are mounted horizontally. Looks improvised, but works very well. I also wanted to use only metal and no 3d printed parts. The end stop uploaded here is practically only the "fear component" if I for some reason would push the slide off the rail when rebuilding. Possibly someone can still use that.
