expanded to a grid (the old way) vs. snug (like the upstream Slic3r, Cura or Ideamaker). Snug supports suffered from the degeneracies when merging overhang islands over a large number of layers when projecting the support towers down. We borrowed the idea & a bit of code from Cura by simplifying the support polygons by closing the concave cracks, see the smooth_outward() function and the MutablePolygon class. Fixes Support problems with models with hole in the walls. #555 Fixes Support in the Air #740 Fixes [Bug] Supports generated beyond bed edges (X<0 and X>250) and where none are needed. #902 Fixes Unable to remove support material/can't change support "inflation distance" #2708 Fixes FR: support inflation and support conform to boundary #4783 Fixes Support blocker not working on this model #1346 Fixes Unnecessary support material #1993 Fixes support blocker enforcer issue #6240

Version

Operating system type + version
Windows 10
3D printer brand / version + firmware version (if known)
Prusa Mk3s
Behavior
When slicing support material is placed inside holes where it cannot be removed (if the hole is longer than a normal drill bit). This is not the case when using simplify3d, which doesn't place the support material along the sides of the part. Even when using support blockers inside the hole, this material is still there. There is also no option to reduce the distance that the support extends outside the part boundaries (not the minimum distance of the support to the part), similar to the extra inflation distance in simplfy3d. This would help to avoid this issue.
As it stands, this support material can't be removed and blocks a mating part, so I've had to use simplify3d to slice this part. It would be great it there were some options to avoid this problem in the future in prusaslicer.
