- Im not entirely sure how the hollowing is accomplished, but it looks like voxel based, shouldn't increasing the precision mean more / denser / smaller voxels?

- The way the program is hollowing at the moment create a lot of 90degree overhangs, which will make printing the inner part problemetic / and or use too many supports.

- Using denser voxels will smooth out the transitions a lot more and give better results.
- I also see the hollow generating empty air tight pockets, this will cause suction / vacumm issues

- Also there should be an option to remove hollow and not relying on undo.
