You might have to if they look sufficiently weird on the scan. But your end of the conversation is unlikely to be much more involved than "Yeah, that's my bag", "It's a bunch of eclipse viewing glasses".
I once brought a carry on full of random electronics/cables, including a partially disassembled desktop power supply in a "custom made modular plastic enclosure" (read: box made out of Legos, complete with a Lego door for the cables to pass through). To make matters worse I was in a rush while packing so the cables were a huge tangled mess.
They flagged it for further inspection, unsurprisingly, but the agent was pretty amicable, I didn't really get any grief
