It's just a way to recognize what keys go to what machine. I should just get a lawnmover robot but hey, there is no drink holder in those!

This is made for Bambu Labs printer with AMS unit, but I'm sure it can be printed in other ways too.

The key fob is double sided! There are two files, one is just 80% sized (not the height) and with that one I suggest printing it with 0.3 layer width!
