XLR Splitter Box
 

I used it to make a simple connection wiring a single XLR female to 4  XLR Male connectors, but you can do it in any way you want to.

It's possible to use any connector that fits the standard Neutrik Style of panel mounted connectors as long as they fit in the connector holes and have the screws in the same place.

I included the connector diagram drawing image in the model.

I plan to do one with a RJ45 input to breakout to 4 individual XLR (Male or Female) over an ethernet cable.;

I used 14 x M3x8mm Socket Head Cap Screws from this set, without threaded inserts.

But I recomend using this one BT3 Socket Head Cap Self Tapping Screws  or this one M3 Socket Head Cap Machine Screws, Keep in mind that their head size maybe different from the ones I used.
