Predator MK8 Cooling mod.

Like Doc brown once said "If you're gonna design a Time Machine, why not do it with some style!"

I have a few cooling mods that didn't make the build plate I also will release, Aliens themed, Doctor who etc. I made this for myself, for fun - it's not perfect but the first print was good enough to use, could have some improvements but as I said, it was just a fun project, I never really intended to upload it but meh, why not.

Unlike alot of other cooling ducts, this is not designed to blow on the tip of your print. This was designed for a large format printer. I am printing up to 400mm wide and fast, so the airflow needs to be more directed at the bed rather than the tip for my needs. You can of course angle the pipes in Blender or another modelling program if you need more of an angle.

I recently got a Wombot Modus and wanted to alter the cooling in it as the stock one was too aggressive and also cooled down the nozzle too much during the print rather than just the plastic which led to some dramatic temperature drops and cold extrusions. I wanted a cooler that wasn't too full-on, but did the job. It has to clear the MK8 offset, and also allow for the air intake from both fans and the filament to feed cleanly, and this was the one that seemed the most logical (RIP Spock)

• Uses a 30mm fan (same as on most E3D extruders) and screws directly into the front of the existing extruder assembly.

*NOTE - You will need to cut a very small notch out of the box for the wires of the 30mm fan, It was an afterthought and instead of re-printing the entire tubes, I just made a small notch for the wires to come through and still allow the box to snap tight.
