FANG Fan cover
thingiverse
Those pieces are custom covers for forty-millimeter noctua fans, specifically designed for use with the CR-10 Fang (available on Thingiverse at https://www.thingiverse.com/thing:2683629) on my Alfawise U20 printer. The top cover is screwless, featuring pegs that fit snugly into the noctuas' holes, while the front cover is secured to the fan with screws. One pleasant surprise was that these covers prevent my front fan from blowing air instead of drawing it in. The parts visible in the photos are final prototypes printed at 0.3 millimeters resolution, resulting in a quality not representative of the best possible output from the 3D file.
