About this model

If you use this fan duct & think it makes your prints look better, don't forget to TIP! ;) This is my version of the "circular fan duct" for the Anet A8 printer (and other compatible printers). Highlights: - it's actually semi-circular. The circular one deforms after a while if printed in PLA (and I use/have only PLA), so I designed this version. - it snaps to the fan a lot more securely (on the outside of the fan), and there is no chance of falling off during print. - designed in such way, that the air blows just below the tip of the nozzle. The original design was blowing too far down. Designed in Blender, by heavily modifying - simplifying the mesh, adding the new attachment part etc. Note: there is newer, and more effective fan duct I designed:
