Amp Meter for 50W Laser

In order to not overload my 50W Chinese laser I need to know how many mA it was drawing. I printed this simple housing for an Amp meter. I then drilled a 25/64 hole in the top of the laser cabinet for the wires mounted the box using double sided tape. I have included a web site explaining the wiring and use .
