Ledring and z-probe holder prusa_i3

Wanted a Z-probe on my Prusa i3 for auto bed leveling.
Already made a led-ring to have some light on the printer.
So got a Inductive Proximity Switch here:

for a few euro's and made a holder for it on my led-ring holder.
It’s not yet connected and configured. But let you know how it goes.
