*** I’m no longer posting to Thingiverse, or Updates. If you wish to see all my work and updates to items posted to Thingiverse please visit my personal website https://gallaghersart.com/design ,OR Google “GallaghersArt 3D” (GallaghersArt is a single word no spaces). Thingiverse was fun! Update Apr 29 2020*After some use, I need more airflow while walking and physical exertion. Also my hotend temp probe failed while I was monitoring thankfully shortly after posting this. My hot ended up being over 350c and fried and burnt the hotend. So I have stopped printing and design modifications until fixed. I rather not post other designs until I can verify all good. I also have a dial to control fan also allowing the unit to be turned off. This is still in beta, current STL does not have hooks for straps yet, updating today until finished. Please visit my website for more related material and just more. http://gallaghersart.com/page/airtight_adapters_for_medical_masks_and_face_respirators This uses my Powered filter design and CPAP Hose from below link or my website for more info and more https://www.thingiverse.com/thing:4266243 I’m upgrading a custom face mask to support Powered Air-Purifying face mask that will use a new / clean trash bag to cover head and shoulders. I do not have any clear covers on hand, but they would be taped to visors front. Then a trash bag would be taped on top of visor and on the edges of the clear face mask. NO cutting clear cover, just tape top of sheet to bottom side of 3D printed visor. Visor can use 8x11 in both portrait or landscape to better meet individual’s needs. Also, if large sheets are cut then the face could be 11” width and any length. The goal is to have filtered air being supplied just above eyes with air flowing over nose and mouth. NOTE!! Does not protect others if your sick / no out going air filtering. Using a disposable mask or my Modified 3M 6300 face mask will help or solve that. Once My design if finalized I will be making it more printer friendly and faster, currently took 6hrs+. using 0.4mm nozzle, 0.5mm line and parameter width, 20%infill, 3 parameters. The battery and fan motor will attach to the persons belt or other support. Stand in place person could get rid of the batteries and just use an AC / DC Converter matching voltage you require (sitting 12-13v, walking 15-17v, max when using on 24v fan is 24v) Work in progress: Support straps to wrap around head and top of head. Top of head and back of head will also support the hose so that it goes behind the persons head. Template to cut from trash bags, then tape to face mask and clear cover (clear cover and trash bag would be single use, just replace when needed.) *Please Note: All the filters and masks you see that I have purchased were purchased long ago for my personal protection from fumes and VOC when needed. I would love to make more for other masks and such but do not have the resources or products to test / make mods for. Donations will change that. Enjoy! `mike Category: Household
