A small nozzle attachment for the "Hurricane O2 Canless Air System"
All the available attachments have such large air holes at the tip, this should give more air pressure for better cleaning of small nooks and crannies.
EDIT: I JUST finished printing it and OMG it is SUCH a perfect fit, suuuper leased with myself :D
unfortunately it seems to be too restrictive for airflow, I'll need to revise it at some point, it still might be useful for a really small spot but doesn't achieve the extra air pressure I was hoping for.
Be sure to rotate it 90 Degrees so the large round end is at the bottom, from there it should print as is, just make sure you get good adhesion to the print bed which can be problematic with such small surface area.
