So funny story, Coco was making this reel demonstrating how our heat sinks are used. The center of heat sink worked as designed and expanded within the BB2040. After making this reel, Coco needed to compress the expansion. She used zip ties to ease the brass center out. Luckily both part separated without damage! Whew!
