[title] 3D Parts
[* black] Bunny PAPR and its fittings are made via 3D printing. The loop, fan mount and air connector blocksfan flange remain inside the bag and are reused after cleaning
[* icon_note] Bag penetrator filter adapter and flutter valve fittingsvalves are outside the bag and must be replaced or sanitized between uses. Soak PETG parts in 70/30 IPA x 5 min+ if unable to dispose between usesreuse is desired. Ideal is to print enough penetrators so they can be single use.

[* black] I print PETG with higher temperature than usual to enhance interlayer fusion. My usual nozzle at 255C/260C, bed 85C/90C, 0.2 mm layer height, 3 perimeters, 4 top / bottom layers, 20% gyroid. Higher temperature than usual is to enhance interlayer fusion.
