I don't know about you, but after I mounted my AMS Lite on top of my A1, I was constantly confused about which slot was which!

Here is my solution for this - simple number tabs that attach to the front spool holders. They clearly identify the 4 slots by using large numbers for the front, and small numbers for the back.

Now, the spools rotate, meaning the numbers will not always be straight, but the small and large number system is obvious which is which.

At a quick glance you will be able to quickly identify which slot is which.

Important notes

• attach the number tabs using double sided tape. I would strongly suggest not to use glue as you may not want it to be permanent.
• wait for the print to cool before removing from the plate! The final print is quite thin, and forcing it off the plate may warp it.
• the numbers are 3 layers to ensure more transparent filaments can still stand out - matte will generally work best, but not required at all

Tip: when choosing your colors, pick ones which strongly contrast with each other. The whole point is to quickly identify which slot is which.
