This is a reduced stl file based on 3dbenchy.stl from: https://www.printables.com/model/3161-3d-benchy

• Number of facets is reduced to make it more manageable for import, file size is under 900 kB.
• Text removed.
• No errors detected in PrusaSlicer.

I also added a FreeCAD file with this model prepared as a Part Design Body.
