Creality Ender-3 adjustable Z-stop

I made my own version. I do not like protruding parts, so I designed my own that can be slided directly into the rails
What is needed only long M3 screw and I nut that should be inserted into one of the holes from the left (not push too far, otherwise there will be no way to repeat the process).

I just have tested separate parts, but not whole thing because I installed BLtouch and this is no more longer needed. Neverless it should be usefull for comunity.

I attach the video how it works or where it should be installed (not the best but better than nothing).
I attach two versions of part "A" - one is for the Ender with glass bed, or bed that is lifted by 3mm more than the stock.
