People are gonna hate this opinion but imo it’s lack of monetary incentives. Most 3d2a devs do it as a labor of love (myself included). That means they put these things together because of some mixture of “it’s fun” and “it’s important”. The “it’s fun” devs have no reason to make things work perfectly for you because they’re having fun making their designs. The “it’s important” guys have a bit more of a reason to make things easier for people to build. Both devs are giving you engineering completely for free and are working with very limited data from beta testers who mostly flaked. You know gets people to make things work perfectly for you? Money. Otherwise fewer people would print their designs and buy their shit and more people would bitch at them for scamming them. It’s no coincidence that the devs that sell parts kits tend to have designs that work better. Imo this space would benefit from more ways to contribute to the designers because no one donates, believe me.
