Print-efficient Kallax Gridfinity Baseplates

I have a lot of Kallax drawers. Most of the inserts I found require 4 plates to be printed to fill up each drawer. For my 20 Kallax drawers, that meanst 80 prints on my P1S. That's a lot of prints to just do the baseplates - before even getting started on the bins! Who's got time to keep changing the prints all day long? With this arrangement, it now takes 3 plates to sort 3 drawers… so to sort my 20 drawers I just need 30 prints. What will I do with all this newly acquired free time? Probably I'll use it to print more gridfinity bins…
