NVG power supply box

## Annotation

Power supply to replace russian NVG "PNV-57E" PSU.

As a replacement PSU I used some chinese high voltage converter and couple of AAA batteries, connected in parallel.

Unfortunately, I found that ABS is not enough insulation for the 20 kVolts supplied, so use at your own risk. I think printing in PETG, adding a layer of conductive inside (connected to output ground) might help, along with filling insides with some insulation compound (paraffin, for example).

## Construction

The design consists of six parts - three for box and three for switch.

### Box

Lower part (Case.stl) has a compartment for a high voltage converter, a place to put battery block (Battery.stl) into and two side holes for wires. There is also mounting "brackets" for straps to attach it to helmet.
Lid (Lid.stl) is attached by 6 x M3x12 DIN912 screws.

### Switch

The complete switch assembly consists of switch case (Frame.stl), knob (Knob.stl) and a switching shaft (Shaft.stl)
