So I never had good luck with cooling PLA properly and I noticed that most peoples filastruder builds had somewhat rickety looking cooling solutions. So after several iterations, I came up with this. Designed in SolidWorks and working well so far. Let me know if you need that part file (its a little sloppy)

A strange print for sure, but if you have good supports and print it with the rear of the cylindrical clasp as the base it should work ok.
