25x1.5mm to 3/4" NPT Adapter

I made this for a 50 AMP outlet box I found on Amazon.   Joinfworld 50 Amp RV Outlet Box 25HD Adapter.  ASIN B0D142ZXQ7.

I could not find a reference to a 25HD thread pattern.  I initially tried a 2mm pitch, but it turns out it is a 25mm x 1.5mm thread pitch into the box.  I am using ¾" conduit based on the NPT spec, so behold… a metric to imperial conduit adapter.

Now I can install a charger for my Mars lander project.
