Optical Endstop Z - height adjustable - probe passing through

thingiverse

It's preferred dark filaments that do not allow the passage of the light, otherwise, like the green ASA in the pictures, you have to use a black tape to cover the probe pin. Check electrical pinout (pin order) that are different from stock phisical endstop. Use double sided tape to stick the probe to the bed support. Use clear glue to cover the led (if necessary). You can use the hole inside to pass a cable tie.
