K1 5020 fan duct

UPDATED Oct 2025 with revision 1. Changes made to better fit the blower, especially the right side screw hole. Still not perfect, but improved significantly. Will update it again when the fit still being slightly off starts to bother me. Remix of Hi0beczek's low profile K1 5015 duct to fit an NMB 5020 blower. The form factor of NMB seems to be slightly different from other 5020s to the point where at least one other design for 5020 fans did not work for me, so your mileage may vary with any other 5020. This is a quick and dirty remix. It's not quite perfect (as made clear in the photo) but it performs perfectly well. Will update this remix as I refine it in the future. I printed it from Overture Easy Nylon (PA612). No heat deformation so far, but glass or carbon composite PA6 will be safer. No modification was made to the spring plate.
