After playing with multiple versions of coolers, remixing few more and applying different revisions, I'm happy enough with this one to share online.

Triple exhaust port, internally angled in such way that it's not blowing the air on the nozzle but just underneath it - in my case the concentration point is about 2mm below the nozzle, it fits stock effector on Kossel Linear Plus and it works with stock probe without any issues.

IMPORTANT - it's got an internal structure to support it and make printing easier, make sure that you only generate supports from the bed - not internally - you only really need few supports for the exhaust ducts for initial bridging, if your printer handles bridging well enough you may not need it at all.

Hope you enjoy it and let me know your results, this one seems to provide more concentrated and effective cooling at lower fan rpms than the radial coolers I've tried before.
