You know, I hate commercial poor quality plastic components, so I decided to build from solid brass a nice looking LED holster.
I also built custom nut from hexagonal brass rod, an easier job than looking for where I put the nuts already made .
As usual, M10 threading, because I like. I drilled holes for the high brightness 5mm unit. Hand polished with lathe.
I will Mount this on Lm amplifier, in next future I will build, for sure, for plasma unit and Esl headphone amplifier.
Commercial parts, here available, usally are in plastic or bad light metal, with a soft chrome that turns in rust very fast. They can be used as indicator for power or services.
