ABS Anet A8 fan shroud (Anti-warp measure)

cults3d

I thought I had finally conquered my warp woes with an airtight enclosure and thermal insulation, heated to around 50c via the bed during printing. But when I started a lengthy print with ABS, disaster struck at the 15-hour mark - the tiny breeze from the extruder cooling fan was to blame. This clever shroud redirects that air upwards, solving the problem once and for all. Secure it in place with hot glue or your preferred adhesive (ABS glue, CA glue, epoxy - the choice is yours). Feel free to drill holes and add rivets, screws, or bolts if you prefer. Mount this shroud on whichever side your fan blows towards - or install one on both sides for added peace of mind. The axis should still clear the entire printing area even with dual installations. This design is specifically tailored for Anet A8 Gen2 printers (with a motherboard reading "v1.5" but should work on all A8 models and possibly Prusa I3/Tronxy variants as well). You can print it in almost any orientation you like, and the process itself doesn't take long at all - with a minimal use of filament to boot.
