Made the base in aluminum, with 50mm diameter and 20mm height. And the seat for the copper plate was made from black plastic.
A small aluminum threaded cap was made for the aluminum base. A slot for tightening the cap with a coin was made with a slotting saw.
The milling tool height probe complete with the copper plate and a small box with two 1.5v batteries and a small green led connected with a 47ohm resistor. As the milling tool height probe acts as a simple switch, can be used with a led with a power source or with cnc software.
