This is my first upload, and it is a work in progress, I did not test it yet with a 80mm fan, when I receive it, I will test the air flow. If anyone knows how to calculate it and can tell me how to do it or which program could I use, it would be awesome.
The photos which are available right now, shows only my 60mm fan prototype, but with a 6010 fan (60mm x 10mm) it doesnt have enough air flow, but at least you can see that it is actually printable. The new fan is 8025 (80mm x 25mm), I have high hopes on it, we will see.
the curve path of the fan adapter created small holes arround it, so i had flat them to solve it.
As the hero me model, this one has to have special supports, and the have to created by hand. I added supports, for the lower middle part, and also covering all the 80mm adapter.
While removing the supports, take special care with the holders, if not, you probably will break them wasting all that time and plastic.
