as part of my journey learning 3d modelling, using Fusion 360, also made this basic fundamental - not following tutorials, just trying my own approach based on other videos I have been going through - getting to know not only the software but how to think about 3D modelling itself.

as i send directly from fusion360 to bambustudio, this is the .3mf file, you can import geometry only into your slicer
