Prusa XL Spool holders numbers - Numbered bases - 1 - 5

I wanted a way to quickly see which spool on the side of the XL was loaded in the tools. This is my solution.

I modified the base part to add a tab which I can then add a number in Prusaslicer. I've included projects with 1-5 for 0.4mm and 0.6mm nozzles. I went with 0.4mm in the end as it gives a better result for a small print. 

1,2,4,5 replace the original base. 3 I used the spare fame mount and a m3 bolt from the spares to fix the 3 to the front.

I realise Pruse have some injection moulded mounts so I doubt these work for those. I cannot test as mine are printed parts.

Feedback welcome.

Ive added a tab to the base of the spool holder so that a number can be added in Prusaslicer
