K1/K1 Max extruder aquarium air cooler

This is an Alpha version.

This design uses an aquarium air bubbler pump to provide room-temperature air into the K1 extruder.

Printing this part as provided will end up only needing a few supports; I have found that a brim is needed to complete the print (brim 2-layers, 10-outlines, 0.05 distance). 

Needed:

• PTFE thin wall (2.5-3mm ID): I found mine on Amazon.
• Aquarium air pump: I went with one for 20-gallon aquariums; I figured it should provide enough airflow since it can overcome the water in a 20-gallon tank. Mine is a Topfin AIR-2000; I also got the tubing to connect this to the print.
• PTFE couplings: you might want to find out if this setup helps you before finding these; I salvaged mine from some air couplings I had. If you're going to do the same, these can work after you recover the end parts.

Let me know if your couplers have a different mounting size (see photos); I can adjust the print and message you to try before adding it to this Printable.

To install the couplers, heat the mount point with a heat gun or a clean soldering iron, then press in the coupler; this should keep the layers from cracking open at the coupler.
