Human: 3M P100 Bayonet Type 20xx Filter Cover _____________________________________ This filter cover provides five key advantages: 1. Prevents accidental contact with the filter, which may contain filtered positive particles/droplets when used in high-exposure areas. 2. Protects the P100 filter from damage caused by cleaning with isopropyl alcohol or other sanitizer solutions that compromise its electrostatic properties. Simply wipe the cover externally without opening the top cover. 3. Extends the life of the P100 filter, allowing for prolonged use beyond the recommended 40 hours or 30-40 days (whichever comes first). This is particularly valuable when filters are scarce or difficult to obtain. 4. Embeds 3M bayonet type male and female adapters within the base, making it easier to remove the filter for storage and sanitizing purposes. 5. Compatible with both half-face and full-face 3M respirators, including models 6200, 6300, 7502 (half face), and 6800 (full face). _____________________________________ Printing Instructions: This filter cover is optimized for printing using nozzle sizes of 0.4mm and 0.8mm. The provided images were printed with a 0.8mm nozzle at a layer height of 0.4mm and a speed of 60mm/s, resulting in a coarse texture. Two separate files are included: one with a male adapter and another without. Printing the base with a male adapter requires support material, which can be difficult to remove. Instead, print the separate male adapter and base files, then glue them together using industrial-grade two-part epoxy or Fevibond adhesive. A washer is required for creating an air-tight seal between the male adapter and the filter cover. A foam roll can be used as a substitute, but other materials may also work. The top cover is designed for friction fit, eliminating the need for screws or snap fits. Once closed, the filter cover will only need to be opened when changing filters. Printing in white color is recommended, as it provides a smooth finish and easy cleaning. Applying a thin layer of clear resin can further enhance the design's functionality by making cleaning easier.
