ok, thx

for as long as I had CURA, I've had problems with my models (I designed) getting their holes filled in. Every time it happened, I just fiddled around for like 2 hours and got it but I have no idea how I did it. I did a lot of research and nothing worked like "union overlapping volumes" and other small settings. I used Fusion 360 to make it and im using CURA 4.7.something. No matter the hole size, they always get filled in. I first though that the walls weren't "air tight" but that doesn't seem to be it. I changed pretty much every setting in the list with no luck. Is there some obvious setting that I have to flick to fix it? or is it a model problem? I've run out of ideas for why this is happening. :\ sry this kind of sucks, im pretty bad at explaining things xD the model is kind of odd because I would upload it one way, no problems. (besides no holes) and I would do it a second way, and it shoes this (images) Gear (Reloader) v1.stl
