joynny v is right.
Even with active cooling for thin pointy things you're better off with a second print.

Rather than a cube - either print two different wings at the same time or two of the same wing. That way you not only end up with what you want - but also allow time for layers to cool.

I had a tiny rubber tube I printed recently and even with cooling I had to do two at a time to give the plastic enough time to cool between layers.

In fact slowing the print speed down for small prints actually makes things worse, as the heat of the nozzle itself remelts the layers - the slower it moves the more the previous layers stay melty.

Arguably you could maybe speed up the printspeed. But it's still not as effective as printing something else at the same time.
