Parametric Spaceship Fan Duct for Anet A8 by frol

Last crawled date: 3 years, 1 month ago

Parametric variation of the Spaceship Fan Duct by paul0. Using OpenSCAD You can change most of it's parameters, including:
duct height
duct nozzle shape (width, height, etc)
duct nozzle inclination angle and distance from hot end nozzle
various size and placement parameters
See section below for animated parametrization demo.
Included STLs are for Anet A8 extruder with Volcano heater block.
To customize You will need the dotSCAD library: download the zip archive and extract it alongside fan-duct.scad. Here is how to setup and use OpenSCAD in the customizer mode. fan-duct.json contains some presets for OpenSCAD customizer.
You may choose model with either vertical or horizontal printing orientation, both models require support from the build plate for printing. Vertically oriented model takes less support material and prints faster, it also has builtin supports for the intake wall.
There is also a test part for the clip-on fan intake, so You can print one and test how it fits your fan before attempting to print the whole duct. Intake parameters can be adjusted in the scad file.
The resulting STLs are relatively hi-poly, this may cause print stalls. You may want to limit the model resolution in your slicer to overcome this (e.g. in Slic3r set Print settings -> Advanced -> Resolution to 0.05). Other option is to decrease $fn in fan-duct.scad (e.g. set $fn to 16).
