@@Kenneth91619 generally you need the model to be designed multipart which is a decision you would make when designing it. Some models you can find on the likes of printables may be multi part already. You will struggle to convert a single stl into multipart though.
@@Kenneth91619the model’s location in the 3D modeling app- even if they are exported individually as stl or obj, if prompted say yes to the question about them being parts for a whole model and Bambu studio (and orca slicer) will give them their original locations instead of dropping them in the center. The parts so long as there is no occlusion, can be exported as a single file which also lets you use the exploded view and exploded ratio slider to move them apart. Mileage may vary. Don’t expect a downloaded file to be set up like this but when it is, it’s a bonus
