What exactly are those white plastic washers?

I have only a few spares, and I have a bad habit of accidentally losing them during disassembly. Are they something commonplace that I can source locally or through amazon/aliexpress?

By "white washers", I'm referring to the two translucent white plastic ones that are on the hinge of the extrusion idler.

They are spacers for the hinge on the extruder idler gear cover

McMaster-Carr is a great place to get parts like that. There is typically a wizard for selecting materials, properties, dimensions and features. I don't know exactly what those washers are because I didn't pay very close attention. They may be nothing special.

In McMaster-Carr you could look for plain washers or else "shims" and look for something around 0.115in ID (please double-check my assumption of an M3 screw). Screws often run a little small so I look for things a few thousandths under for a better fit.

perhaps this one?

here is a Mica one that might work, but be aware they are likely to be on the brittle side.

I think this is what they are Form A Washer M3 in Nylon - ISO 7089 (DIN 125A). I have brought loads of extra M3 screws and nuts from them for my various projects.
