I wanted to replace the old Analogue Voltmeter with a new LED Voltmeter.
I designed this frame to mount the new LED voltmeter in a frame that match the old meter looks and dimensions on the face of the PSU.
The second version have the LED meter face sunken to be level with frame.
Hole for LED Meter width is 45mm and height is 26.5mm
Use 4 screws to mount from back, 4mm diameter x 6mm long ( holes are 3mm )
