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.

    Can’t remember what brand specifically. Generic brand for sure. Id have more faith in polymakers blend.

    I preheated my chamber, set my build plate to 100c and print at 270c. All fans off.
