ok skipped a few experimental versions.. ** now up to V10 **
Latest version modeled with CFD to improve cooling at the tip of the extruder head.
I have managed to print some very small delicate parts as a result and the quality is definitely better.
the design blows air from both sides with a slight asymmetry in order to get the 2 paths to pass closer to the tip.
there are supports in the model that improve the printing of the V section under the fan these are designed for a 0.3mm nozz
