After all these months, the rotor is no longer just a digital CAD design. 

Looking at the stickers, it seems the package was delivered by 4PX and Evri, so it's unlikely that a courier is going to send a scary letter 4 weeks from now. ABM put a lot into the packaging, using metal U shape pieces inside. There were also documents relating to the rotor measurements, such as a gauss graph over 1 revolution. 

Below is a collection of images I took of the unboxing:

Both of these docs have a few bits of data that I don't yet know the meaning of ( e.g. kG*D, Cp, Cpk) but I can gather the geist of what these docs are talking about, so I don't think I'll need to be talking calipers to the rotors.

Me whilst looking at the contents, feeling like I'm engineering like an enterprise:

All these formal documents! All these intricate metal assemblies!
