I’ve had several models now that I’ve had to print with a hollow opening in the bottom. These openings are sometimes 5-10 cm high, but only 1-2 cm in width/length. So I have a very tall line of support material that is surrounded on 5 out of 6 sides by solid walls. How do you break away support material in this case? Even when I tell Cura to leave a wide x/y gap, it still connects the lines to the surrounding walls at the ends. Is there any good solution other that water soluable support material?
