Sink Plug

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 lengthI 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.
