About this model
Why All fan ducts suck. This one sucks less (I hope!). There are several reasons: first, it does not restrict air flow (each branch cross-section is 1/2 of the inlet). Second, it maintains laminar air flow. Third, it provides even cooling from both sides (good for PLA plastic). Fourth: it's completely customizable, just load it into FreeCAD 0.16 and edit variables in cf spreadsheet. Designed for Anet A8 (Hesine, Omni, etc), but you can change parameters to fit it almost anywhere. Use heat shield This fan duct cools heat block a lot, so insulate it or use some kind of heat shield (I made one from cotton stripes and kapton tape). Look at the temperature graph: without heat shield temperature swings cause serious wobble that looks almost exactly like z-woble, but wobbling disappears when heat…
