PLA cooling fan mounting bracket

Without cooling, I couldn't print any post on the object because the PLA is still too hot and soft before the next layer comes on.

So finally I designed this bracket to mount a 12V 5015 blower to the printer.
And the result is great.

The fan is common 5015 turbo fan blower, you can find it on aliexpress.

If you don't have one, and printing twisted posts, this is your solution!
