Summary

edit: at this point I don't recommend this as it performs slightly worse than the original cooling nozzle.

Playing around with cooling nozzles. This is an alpha rev and has only been moderately tested.

Print without supports and break away 4 tabs shown in red and listed as breakout in the 3mf file.

I added an STL file because Thingiverse wouldn't allow me to post a 3mf file only.
