LaAnchoria COVID-19 mask - 2 models - 5 sizes each
Description
LaAnchoria is a mask design combining multiple characteristics of several prior designs. Created in Anchorage, Alaska, USA. Originating design is LaFactoria3D v1 -- https://www.thingiverse.com/thing:4225667 Billings Montana then modified the facial profile (wider) and filter -- https://www.makethemasks.com/ Rat_Patrol's 3D Printable Mask/Respirator v1 then modified the filter section of the Montana mask -- https://www.thingiverse.com/thing:4236172 Additional resized and labeled options of these originals: LaFactoria3D v1 -- https://www.thingiverse.com/thing:4239753 Montana -- https://www.thingiverse.com/thing:4247368 Rat_Patrol v1 -- https://www.thingiverse.com/thing:4261811 Masks are symmetrically re-scaled in the x and y direction only. The z direction (direction of nose sticking out of face) is left unscaled. LABELS: Z = 105% A = 100% (same as original) B = 95% C = 90% D = 85% The LaAnchoria name gives credit to the original creator of this style of mask, LaFactoria3D, and recognizes the community creation from Anchorage, Alaska, USA. Model L = "LaFactoria3D v1" facial profile (narrower) Model M = "Montana" facial profile (wider) The facial profile sections are exactly identical to the LaFactoria3D v1 and Montana masks. Characteristics: -Larger opening for filter material -Breathing and talking easier for higher MERV rating material and/or multiple material layers (for example, surgical sterilization wrap) -Designed to utilize multiple types and layer(s) of filter material -Easily replace filter material as often as desired -Easily remove filter retainer ring with removal tabs -Universal filter retainer ring for all sizes and models -Standard (S), loose (L), and tight (T) fitting options -Retainer ring gaps: loose 1.6 mm, standard 1.4 mm, tight 1.2 mm -Sizes extra small - extra large to minimize molding and ensure no gaps -Most people are sizes A-D -Quickly size individuals with 5 mask set of each model -Labeled for easy size identification -Large loops to accommodate multiple sizes of elastic / ties -Print with no supports This 3D model is a prototype not approved by any regulatory agency and has not passed any laboratory tests.
