mA meter mount K40 Laser

I created a mount for a generic mA meter (Amazon: Ammeter Gauge DC 0-50mA Analog Current Panel 85C1) and a drilling template (PDF file). A 1 1/2" hole saw should work, but you might need to file a little bit. The holes are undersized so you can use whatever hardware you want. Just make sure the hole in the print is smaller than your screw so it threads it's self.
