Took quad wall plate into tinkercad. Cut away all but the brim and screw hole borders (this str is included) then in prusa slicer added that to the quad wall plate, Enlarged the additions z dimension till I got the thickness I wanted.    In addition the 3mf file for the XL uses TH1 for modifiers which label the jacks.  TH2 is used for the plate itself.  One could easily add the platethicken.stl to the other wall plates in @rodoca_317174's assortment.  

Using Prusaslicer you can easily change the labeling of the 4 jacks.  The parts are clearly labeled in the 3mf file.
 

The photo of the two plates side by side shows you on the left the original one designed by @rodoca_317174 and on the right my modified one.   You print them on their outside the way they are showed in that photo.

The cover photo shows you a labeled plate.

This is my FIRST model upload ever!  Give me feedback, let me know if you like it.  Thanks @rodoca_317174 I could never have done all that you did.
