I'm currently making a functional minifigure-scaled escalator that ideally move like this. Progress has been made on both the stair slope and staircase design (both respectively pictured below), and now I'm working on a sort of guide for the staircase to transition into flat platform.
However, I've come to an issue regarding the height of the guide being 1 plate thick, as I've yet to find any flat plates or bricks of plate width with the appropriate bevel to prevent the staircase shafts from getting snagged. Currently, the only "beveled" plates that I could think of is the 22385 pentagonal plate, and the 15070 modified plate with tooth and its other variants.
Are there any other kinds of "beveled" bricks should I know of or any legal building techniques that can create a sturdy plate-width edge or slope that could be utilized here? Either way, I want a result such as this image (note the red plates and the drawn-in edge):
It is paramount that this guiding overhang is 1 stud in width or shorter, 1 flat plate tall, and built using only legal techniques.
I am also aware of the dedicated escalator piece but I won't be using it due to the complex nature of my build.
EDIT: This might be an illegal technique, but I might have found a method for sloping, which utilizes a panel atop 1x1 brick with stud on the side and a 1x1 headlight brick joined at the side. This is the base, with the two snot pieces forming an offset stud arrangement on top.
While I have tested this with my available bricks and it works, I still don't know if it's a legal building technique or not, so please inform me.
EDIT 2: I was informed by @Sander De Dycker that this building method is illegal, as the top studs are slightly further away than normal. However, since this slanted panel is very close to my desired outcome in terms of angle (280 degrees as Stud.io informed), I am in search of legal building techniques that produces the same result.
