LED print bed levelling indicator

I have been using, from time to time, the trusted paper feeler method to manually tram the Ender 3V2 printer bed and also create a bed levelling mesh.

The manual tramming method depends on a good and consistent sense of touch, a suitable piece of feeler (paper or metal) and fumbling with both hands. I believe that there must be an easier way of doing this. At first I used a dial indicator with a mount attached to the X-axis carriage (thing:5346325). This works well except that the instrument, small as it may be, is cumbersome to attach and manipulate. Moreover, the test point is offset from the tip of the nozzle by quite a few centimeters in both the x and y directions, skewing the test points towards the front and right sides of the hotbed.

I eventually made this mechanical probe with an led indicator. This probe is equipped with a cantilevered rod with its tip positioned directly below the nozzle. The rod activates a miniature microswitch to light up a small led connected via a
