Laser Cutter Ammeter Housing

Made a housing to hold an Ammeter I've fitted to my Chinese Laser Cutter. I've installed it on the return path so it doesn't have HV on it.

Panel Meter is https://www.amazon.co.uk/gp/product/B00AO83O3I/ 'DC 0-30mA Analog Current Panel Meter Ammeter 85C1 30MA Off White' on Amazon from Sourcingmap

I followed this guide http://lensdigital.com/home/?p=1453 but didn't want to made such a huge hole in the body and leave it a mess.
