Fusion 360 Printable Model Design

I need a straightforward, print-ready 3D model created in Fusion 360. The part is meant for FDM printing, so the focus is on clean, functional geometry rather than ornamental detail. I already have the critical dimensions sketched out; you’ll just convert those numbers into an accurate CAD file, optimise wall thicknesses and clearances for printing, and export both the native .f3d file and an STL.

Once the model matches my measurements, a quick tolerance check and a screenshot of the slicer preview will be enough for acceptance.
