This is a pop up drain plug for sinks.

I had a silver plug and wanted to change to a black one. They are quite expensive, so I made one.

It it is designed to fit a M8 threaded insert (outside diameter: 10mm). I used one with 6mm length

I also used the rubber ring seal from the original plug.

I don't know if it necessary, but I spray painted it.

I sprayed in three layers:

-Primer

-Color (black)

-Varnish matt

Still looks great after som months.
