We already have T54024, T47030 for this.

I dont think this case adds anything new?
Will merge this into T54024 (but feel free to comment again if you think this is different...)

Yeah it looks similar but after watching the video I don't think it's the same.

The cylinders used for cutting here don't overlap with the other object as seen on this screenshot:

But I assume these are considered overlapping [it actually works heaps better if you put modifiers Overlap Thresholdoption to zero in your file]

Not sure but for me it looks still the same? Maybe it's because I'm using the 2.79 instead of newest builds?
