Power meter housing

This is a simple housing to hold a 4 in 1 DC power meter & a 50A/75mV shunt like this one:

The meter opening is 45mm x 85mm.

I am using it to monitor the input power for the laser module on my Sainsmart LE5040 laser engraver. It is attached to the T-slot frame by using the shunt's M5 mounting screws and t-nuts.
