Intended for low-voltage use where the electronics are protected from people/the elements by a case. Quick, dirty and simple due to pandemic.

Good for a DC power application where you need a positive and negative rail.

You need:
Mounting screws (to fit in 4.3mm diam hole)
Terminal screws (m4)
M4 tap
8mm wide nickel strip, cheaply available as a battery component.

Use the part as a guide to punch holes in the nickel, tap the screw holes, mount and use.

You could scale this part for different nickel strips or screw threads.

Don't be a dumbass and use this for high voltages.
