I developed this fang for my Alfawise U20 printer.
In this version, the mounting of the extruder on the carriage is not modified in order to maintain the rigidity of its mounting. The fan and fang supports are mounted with the 3 threaded holes provided for the original fan and fang support.
Parts to be provided in addition to the STL :
2 inserts M3x4x5 https://www.amazon.fr/gp/product/B07CPRHP2X
1 CHC screw M3 x 20
2 CHC screws M3 x 16
2 fans diameter 40 mm such as https://www.amazon.fr/gp/product/B004QZKV68/
8 self-tapping screws M3 for fixing the fans
Update of 27/05/2020 : Shortening of the lower fang
I recommend that you tilt the fang parts in your slicer so that you have no support inside the ducts and thus maintain a smooth surface to optimize the air flow in your fang and thus reduce the induced noise.
The filament that best matches the colour of the Alfawise U20 is CHROMATIK Brick Red.
