This PrusaSlicer project applies modifiers to the original 3DBenchy.stl, with 100% infill for the aft hull and lightning infill elsewhere. The resulting model floats upright when printed in PLA. This version is under 8 grams, but some of my previous test prints were over 12 grams and just barely floated, so there are many solutions to this problem.
floating_benchy_prusaslicer_project.3mf has everything preconfigured, but it may mess with your printer settings.
Alternatively, you can follow these steps to rebuild the project from the provided STLs:
Open 3DBenchy.stl and configure print settings:
- Perimeters: 1
- Solid layers: Top 2, Bottom 2
- Extra Perimeters if needed: Yes
- Infill: 10% Lightning
Right click "3DBenchy.stl" > Add modifier > Load > dense_hull_modifier.stl
Right click "dense_hull_modifier.stl":
- Infill > Fill density: 100%
- Layers and Perimeters > Perimeters: 2
Right click "3DBenchy.stl" > Add modifier > Load > light_hull_modifier.stl
Right click "light_hull_modifier.stl":
- Layers and Perimeters > Perimeters: 2
Enable "Center of gravity" in the Preview window, and verify that the CoG is at the bottom-rear of Benchy's window opening, as shown in my screenshot.
2025 update: I replaced the cutting planes with modifier STLs, so this should be easier to replicate in other slicers.
(To visualize the vertical cross section, I used PrusaSlicer "Export Toolpaths as OBJ" + Blender Bisect tool + Microsoft 3D Viewer in Orthographic mode.)
