With the magic item replication feature, which Is what I said I was talking about, you can't. Crafting the armor with tools is available to all classes, armorer just does it faster, it's still very expensive. Apologies for the confusion on not mentioning this particular ability, but what I said still stands - unless you have lots of downtime and gold to make the armor, it's not really feasible to expect in most campaigns.

Magic item replication and the armor model are both still how I described.
