I had another go at printing mooncactus gopro connectors (https://github.com/MoonCactus/gopro_customizable_mounts) this time I used 0.15mm layer height and supports, printed with PETG.
This worked, as in everything fits, however I still got some curling on 2-prong connectors.
Usually when I print with supports filament sags, so having 0.2mm interface distance is what needed, however here the filament curls up, so I need no interface.
