I don't really understand why you should need this?
I use the E3Dv6 hot end drop in cartridge all the time without a flag extender. There is even enough room to have a glass plate on top of the bed without any problem.

Because i will not change the original settings too much (Z-Offset and Screws) and i don't use a glass bed only BuildTak. This very simple "AddOn" makes it easier for me to calibrate. And maybe for others too, thats why i sheared it. ;)

Oh, I love the sharing part :-)
I only don't understand why it's needed. Indeed, change the Z offset a little and you are on the safe side.
If this printed flag get's of just a little (because of temperature changes, for example) it will probably hit the opto coupler and damage it.
I am well willing to risk damage to my printers if this is needed, but in this case I just don't see why it's of any use, at least not for the Da Vinci Pro. I don't know about the other models you mention.

Really, this is not to be rude to you, but I am afraid this is a bit risky and can cause your printer problems in the future and I don't wish that to happen to you.

$2 isn't a lot of risk. https://www.geeetech.com/opto-optical-endstop-end-stop-switch-p-682.html I find the flag very useful as the E3D replacement print carriage I designed sits about 6 mm lower than the one that came with the system and the flag makes it easy to set a new, much lower, z-limit.

Well, I am not talking about the risk of damaging a $2 component. :-)
If this endstop fails, your stepper stays activated, keeps moving upwards and, if you are lucky, burns out your stepper driver. If you are not lucky, well then your house burns down...

I hope you get it that this is just a joke... But I wouldn't do it this way.

Lol, makes sense. You could crash your bed. Point taken. : )

I also created an printed also such a flag, just before i saw this design.
I needed it for the same reasons as mentioned.
However be also careful. 6 mm extension is fo a DaVinci Pro 3in1 the absolute maximum. When it goes down after competing a print i t just hits the rotating plate of the scanning feature (From the home position it goes 19 cm down). For a DaVinci Pro it might hit the bottom f thecae (Max distance from home 20cm)
