This is a Artillery Sidewinder X2 fan duct for two 5015 fans. This part is not optimized for FDM printers. It can be printed with a lot of support but is easier to print on an SLA printer. I can recommend Sirayatech Build Resin.
There is also a plug that covers the mounting hole. This should be printed in TPU/TPC or TPE filament. I recommend TPC, it is very easy to print and has a good adhesion to textured PEI sheets.
What you also need:
1x M3x52 or 55 Screw
2x M3 washer
3x M3 nyloc nut
NOTE: The blue stepper cover will most likely not fit. I cannot test it because my sidewinder X2 is modded with a IT&E Wiring Upgrade Kit.
If you want to modify the duct or like to remix it you can find the STEP assembly in the attachments!
The author remixed this model.
Fan duct completely redesigned. Added option for mounting the blower fans with a screw. Smoother duct channel transition. Lifted right duct 2mm up because it sits too low on the original design.
