In the app, if you click the All models button, everything there should be a1 mini printable.
The only problem, I don’t think it’s searchable, you have to scroll through everything. I’m new to this, so there is probably a better way, but this is how I do it for now.
If you select all models, you will see all models.
That list contains all models, it does not contain all models that are compatible with the A1 mini, as they are not. Many new ones are, but, there is no guarantee. Many older models are not compatible with the A1 mini.
You will also find models that will not print on any Bambu Lab print as they have a profile for a different print. Those are rare though. You will find many models with no print profiles and cannot print those models as there are no print profiles to instruct the printer what to do.
You can load all models into Bambu Studio and depending on the size of the model, you can target all printers.
I mention this as it is important people including yourself do not confuse “All models” with “I can print all of these”, it should be thought of as "I can print most of these, I may have to do something to print more and some I will not be able to print.
