Notice

This shroud is obsolete and replaced by my new design https://www.thingiverse.com/thing:3569037

- - - - - - - - - - - - - - - -

Why?

The original shroud was blowing against my nozzle and indirectly cooling the part. I changed the design and pointed the airstream towards the part and away from the nozzle.

Updates

v3 same height as original, changed the opening to better concentrate the air
v2 is ~1mm lower compared to the original design, beware!
