Floating Benchy (density hack) by p1mrx
www.thingiverse.com
This PrusaSlicer project cuts the original 3DBenchy.stl into parts, using 100% infill density for the aft hull and 10% lightning infill elsewhere. The resulting model floats upright when printed in PLA. This version is under 9 grams, but some of my previous test prints were over 12 grams and just barely floated, so there are many solutions to this problem. I used PrusaSlicer because its "center of gravity" visualization is somewhat useful. To make the vertical cross section, I used PrusaSlicer "Export Toolpaths as OBJ" + Blender Bisect tool + Microsoft 3D Viewer in Orthographic mode. The Public Domain license only applies to the slicer profile, as I did not create the model.

    That “slicer file is public domain” part would probably not be valid as benchy has a “no derivatives” licence:

    If you remix, transform, or build upon the material, you may not distribute the modified material.

    That overrides the requirement of “share-alike”, meaning you have to use the same license for remixed or derived content, as you aren’t allowed to release any in the first place.

    Unless the creator has received permission from them, of course - that overrides all licences.
