BB-8 Panel Nomenclature?

[kresty]

Hmm, was realizing that if we call the orange round bits panels, then calling the triangle bits panels too might be confusing.

I've noticed that the triangle plates don't all seem to be the same either. They all have 3 "fastener" type things, and the ones I see in my photos have what looks like an access door along one edge nearer one of the fasteners. However some have 4 ticks sort of opposite the "door" and some do not. The couple I saw looked likely identical though.

Eg: the 123 triangle has ticks, but the 236 triangle does not (#'s are of the orange rings surrounding them).

I'm guessing the "door" helps them remove the triangular panel like we saw in the Lee facebook post? Looks about right to shove in a couple fingers and yank off a panel?
