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.

Why did you think it would?
These are your viable options.
PLA plus Pa6cf nylon Pa612cf nylon Pa12cf Nylon Pa6gf Nylon Pet-gf (glass filled PET, not the same as petg) Pet-cf
Ppacf and ppacf are TBD as far as I can tell

Is PETG-CF a viable option too since PLA+ and other cf filaments are?
