Decathlon mask filter adapter, SNAP version

SNAP VERSION NOT RECOMMENDED FOR PLA, USE BOLTED VERSION Characteristics: This adapter model is designed for 3D printing even in deposition machines to enable users to utilize their best available filtration membrane, thus preventing masks from being unused due to a lack of specialized filters. It consists of two parts: the adapter connects to the mask where the snorkel would normally be connected, and the grill traps and seals the filter membrane against the adapter. The filter is a cutout of some accessible filter membrane such as the material found in an N95 mask, a P100 filter, cloth fabric, coffee filter, HEPA vacuum cleaner bags (without fiberglass), etc. Advantage: • The device can be easily manufactured on 3D deposition machines • By allowing various filter membranes to be used, it prevents the mask from becoming obsolete. When resources for different possible filter membranes are scarce, it allows protection even if it is not ideal material. • Disposable N95 masks must be discarded because they lose their shape and stop sealing against the face due to high moisture exposure from breathing and constant user manipulation. With this device, the filter material of the mask lasts much longer since it is less exposed to moisture and its structure is permanently maintained between the adapter and grill. • The device can be easily cleaned with soap and water (without the filter membrane) • The device is more compact, preventing it from extending far beyond the head, exposing it to shocks • A single filter membrane resource can be transformed into several, multiplying it. For example, a single N95 mask can be cut into 2 or more filter membranes • The device can be quickly redesigned to fit different makes and models of snorkel masks • The device allows users to "cover" the grill by hand to perform the face seal test with the mask when inhaling and exhaling with the grill locked
