[title] 3D Parts Post Print & Assembly
[* black] Experienced 3D printers will noticenote this project requires minimal post print processing. Do inspect prints for stringing and remove fine stringstringing with heated air. Remove burrs ifas needed. 3 mm bolt passages are easier to use if one runs a 3 mm drill through them before assembly.
[* black] I have intentionally designed to allow operation without too close a required tolerancetight tolerances. Most of the HALO respirator runs under positive pressure and is not involved in gas sealing.

[* red] Consider lapping the bottom of the fan flange so it seals well against fan body.
[* green] Fan attaches to its mount and flange via M3 boltsscrews and nuts. Length of boltscrew should be just over 5 mm longer than fan thickness.
[* yellow] A single 10 mm M3 bolt and nut attach fan mount to halo.
