Was hoping I got good enough layer adhesion here, and I may have, but cracks formed at the pin holes.

Fortunately did not have this happen while firing. I noticed the cracks when inspecting the gun at my desk, flexed it, and it completely snapped.

Figured I would share as an example to others. Filament choice is super important in 3D2A. Be careful.
