Hemera E3D v6 Circular Duct v3.1 (NEW 6/9/22)

So here is my take on remote part cooling for hemera with V6 hot end. 

This is a remix and partial redesign of AlexMu fan duct design

Duct connection is 20mm OD and 16mm ID. 

• v1.0 and 2.0 -REMOVED-
• v3.1 is a 30% larger, with larger holes for less restrictive air flow, better tolerances around the heat block and now has a HEMERA LOGO

I would strongly suggest using a silicon sock on your hot end and print in PTEG.
