Distribution board screw

A rough and ready Distribution Board screw. Worked for mine, may need tweaking for yours.

Note - check the dimensions of your own application, you may need to extend the length of the thread dependant on the board manufacturer.

I could find no standard thread in Fusion360 course enough to fit my distribution board, so this solution is made using a spiralised triangle that is filleted at the apex. by no means professional quality, but it got me out of a hole.

Disclaimer: Don't touch the leccy box if you can't avoid the spicy wires.
