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.

What kind of asa did you use, have had absolutely no issues with polymaker Asa in any of my builds with rounds through them, make sure you print with absolutely no fans on and heating the chamber prior really helps, looks like it coulda been a layer adhesion issue

That ain't layer adhesion, all the fissures cross layer lines. And the edges and overhangs definitely look like they were printed with no part cooling.
ASA just isn't different enough from ABS to be advisable for frames.

My thoughts as well. I did my research and tuned my settings to get the best results with my test prints. Probably just the cheap blend I got.

I'm just mad the Elegoo ASA isn't available anymore. That shit was $15/kg all day erry day.

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.
