<p>I haven't ran into the issue yet, but I am sort of expecting it to here soon towards the end of my print. Actually, I am not even sure if it should be something that I should be worried about or not.</p>
<p>Basically I have some overhang on a helmet piece (it's a vent piece) and I see that there is a 90 % degree overhang. It doesn't look too big but just curious if this should be something that I should be worried about. I forgot to add support in the vent, it's my own fault and I'm definitely going to fix this in my next print for sure, but do you all think it will fail if I keep the current print going?</p>

<p>I use Cura, Meshmaker, and I have an Ender 3 printer.</p>
<p>I'm just getting started with 3D printing so I wasn't sure if I should be concerned or not.</p>

It should settle in a few layers. Just make sure you have a decent cooling fan on it.\nGiven the fact that you are making a helmet, I assume you are going to sand and apply putty to the whole thing at least 2 times and then sand in increasing grit. A little filing on that overhang will be an easy task.</p>\n"}]
