So it seems like the crucial base mat to make the 220 crafted gear is the new Eikon stuff (mythrite, metal, fiber, hide). There's no recipe to make these and there's no mention of these being added to gathering points. So maybe these are a direct purchase with red scrips? The description on all of these mention that they are 'blessed by a primal' so maybe they are dropped off primal fights or maybe a new purchase with primal tokens? Looks like you're gonna need about 4-6 of these to make a left side piece.

Guesses? (what else do we have to do while we wait?)
