5m/Pro part-cooling duct

I have remixed from: Sergey Sergeev from Printables

just removed unnecessary comb holes that were not fit for printing and failed often.
2 designs that were tweaked,
1st with flow hole on both sides which are functional and solid fro printing at 600mm/s 3.5hrs with 0.4 nozzle only 0.1 layer
2nd with all design covered up and easier and faster to print 600mm/s 3hours with 0.4 nozzle only 0.1 layer

I suggest printing with PetG or anything with higher temp for chasers heat and durability. I have tested and made sure they work with 2mm X 5mm magnets as originals.
Latest one is the revised version with Step file for you to edit and have ago!
G-code ready for (0.4mm nozzle- 0.12 layerhight - PetG 250/260C nozzle temp 60/80C Bed temp)[supersonic speeds 2hr20min]
you will save 1hr with the 0.2layer hight print but its not worth it for the lifespan of the tool.

I am 100% satisfied with the design and than the original maker Sergey for his input.
