Tested and confirmed working for all 4 spool slots!

If you have already printed the awesome Python AMS before RFID support was added, and don't want to reprint the newer version, you can print this and mount the RFID boards at the back of the Python AMS. Use a small dab of glue to hold the printed part in place on your Python and the RFID board is then held in place by a friction fit within the printed part.
 

You will also need 2 * 8pin extension cables to extend the wires to the RFID boards, I suggest [https://www.aliexpress.com/item/1005007188110093.html](https://www.aliexpress.com/item/1005007188110093.html) (30CM, 8P, Reverse direction) so you can just replace the existing short cable.

I used a scalpel to cut out two of the external spool holes to run the extension cables through, and drilled a new 4.1mm hole for the first spool slots external spool PTFE tube, this is shown in the photo's.
