Has anyone managed to print usable vertical holes? The perimeter loops for mine don't stay put so I end up with a clogged hole. While the infill around it is circular, the perimeter loops are always hexagonal and very loosely connected to the infill layer.
Tweaking oozebane and using stretch seemed to help a little, but I'm not really sure what settings will most affect how well a hole prints. Note that this is not the usual ooze problem where strings ooze out of the nozzle and cause straight line threads that clog a hole.
