Has any experienced random reversing of an axis?

You are welcome. Found this about the connectors:

LongBoard Connectors - #4 by chrismakesstuff

It only lists the female half of the connector.

I did a little research and this might be the male half.

Ningbo Kangnex Elec | Ningbo Kangnex Elec WJ2EDGRC-5.08-4P | Pluggable System Terminal Block - LCSC.COM

It’s called a “header” and the female have is called a “plug” and the connector system is called a pluggable terminal block.

Just google 5.08 pluggable terminal block . Add “header” or “plug” depending on which half you want. I did find sets of both.
