thingiverse

LaAnchoria is a pioneering mask design that combines multiple innovative features of several prior designs, created in the heart of Anchorage, Alaska, USA. This groundbreaking design originates from LaFactoria3D v1 -- https://www.thingiverse.com/thing:4225667, a trailblazing model that paved the way for future improvements. Billings Montana then took the lead, modifying the facial profile to make it wider and enhancing the filter section -- https://www.makethemasks.com/. Rat_Patrol's 3D Printable Mask/Respirator v1 further refined the filter section of the Montana mask, taking the design to new heights -- https://www.thingiverse.com/thing:4236172. Additional resized and labeled options of these originals have been created, including: LaFactoria3D v1 -- https://www.thingiverse.com/thing:4239753 Montana -- https://www.thingiverse.com/thing:4247368 Rat_Patrol v1 -- https://www.thingiverse.com/thing:4261811 The LaAnchoria mask is designed to be symmetrically re-scaled in the x and y direction only, while leaving the z direction (nose sticking out of face) unchanged. LABELS: Z = 105% A = 100% (original size) B = 95% C = 90% D = 85% The LaAnchoria name pays homage to the original creator of this style of mask, LaFactoria3D, and acknowledges the collaborative effort from Anchorage, Alaska, USA. Model L features a narrower facial profile inspired by LaFactoria3D v1 Model M boasts a wider facial profile designed by Montana Both facial profiles are exact replicas of their respective originals, ensuring authenticity and consistency.
