These are the labels that work for all of my Gridfinity universal socket trays.

The tray models can be found at the below locations

Standing socket tray

less than 68mm length

68-99.9mm length

Instructions

1. Create a new plate once the profile is open
    
2. Create a blank plate then select the blank plate and right click on each label you need printed and clone it to the new plate, then Print the labels. (There is a blank tag as well if you want to write small with a pen or fine marker all your labels. but I like using multi color and having them printed on. minimal waste with the writing on top and not embedded)
   
    
3. Print a single insert from the insert tray as a test piece. take the insert and put it in the hole on a socket tray. It should fit easily enough to remove with your fingers. If the fit is too tight, Reduce the X and Y axis by .1mm (uncheck uniformed scaling).
   
4. The labels may not perfectly press fit in with all filaments used(i am working on a click fit design to solve this), use a dab of glue and put the pieces together and let dry.
   
5. once you have confirmed the size of the insert piece is correct, right click on the insert and clone as many as needed to a new blank plate and print them 
   
    
6.  Perform step #4 for all your labels then insert them into the tray label insert location
