  • When my Ender 3 S1 (not plus) had bed leveling issues, the problem was caused by backlash on the Z axis. It’s important that the Z axis be just loose enough that downward motion is driven by gravity. If instead the Z screws have to “pull down” on the gantry, then the height will be too sloppy for ABL to make fine adjustments.

    It is possible to smooth PLA using ethyl acetate, but I don’t know if that’s good enough for food safety, plus you have to remove the ethyl acetate itself.

    PLA won’t survive in a dishwasher. PETG might, but there are no reasonable solvents for smoothing PETG.

    Maybe it’d be best to print a mold in PLA, smooth with ethyl acetate, clean thoroughly, and then pour silicone into the mold.

    Benchy was not designed to float. An STL file only defines the external geometry, but if you print it with default slicer settings, the density will be relatively constant throughout, and the resulting center of gravity is too high and too far forward to function as a boat.

    In order to make it float, I put more mass at the bottom/rear and less at the top.
