Recently installed glass onto of my bed and needed a way to adjust the z endstop. I ended up making a simple printable Z endstop adjuster that fits in nicely to the bed carriage. It even has a handy wire run on the bottom for the heat bed's wires.

Very clever! That's a great non-intrusive way to add this capability. Someone else did a similar feature by drilling and tapping a hole then adding a long bolt with a spring as a way to adjust the trigger, but that requires drilling and tapping and more parts of course!
Just printed one of these and it looks nice - good work.
The only problem I had was when I came to fit it, at which point I realized I had assembled my Z axis upside down! I mean I had attached the flanged bearings and the leadscrew nut from the wrong side. Fortunately, it took only a few minutes to fix it. I guess I was doing this part after the beer when it should have been before.
I was working on a similar item but you finished yours first! Your design is also much cleaner. Anyway I printed up yours and had a few suggestions. The plate that holds the endstop is a little too thin and a little too narrow. There is a little to much slop from side to side, even when I crank down on the screw. Thicken and widen up the plate and it will be perfect!
Carlos your design is so simple and elegant compared to what I was working on.
I got impatient and tweaked your design just a little and here is what I came up with:
Changes: Widened the slider to allow for plugs pins to not hit the bracket. Made the tabs on the bracket thicker so I could use M5x10 that I had left. Moved the slider a little further away from the 2020 extrusion so that the endstop PCB would not hit the head of the M5 bolt. Tighten up the bracket around the slider so the system is very solid with no wobble once tightened up.
Carlos do you mind if i post it as a remix?
And I was cutting it a little too close when printing, only about 0.5 of a meter was left when done!
