Ender-3 Vent Fan

thingiverse

So i was having problems with my cooling, so i went on thingiverse and found a circle vent and one said short and the other said tall. So i printed the short one and after a couple days it melted. So i printer the tall one, but it was the same size.So i customized the tall one by 3mm and so far so good, but i want to thank @Fiboyt for making the file all i had to do is make a small change and now we go.
