A side-intake fan shroud for the Creality Ender 3. the next step is to design a connection from the shroud to the side of my printer enclosure, so that the electronics aren't drawing in heated air during a print.
started from adamant 77's shroud (https://www.thingiverse.com/thing:2935204), ended up redrawing the whole thing in sketchup.
UPDATE: 24-12-2018: updated vent shroud with a v3 version, which adds an indexing flange for the other components. also uploaded an extension vent, 40XX-mounted raspberry pi box, and a 60mm fan mount that feeds into both. all files should be printable without supports, though YMMV. if you only want the shroud, print the v2 file.
UPDATE: 01-07-2019: removed 60mm fan mount. will re-add new design in future update.
