Respirateur portatif V2

thingiverse

The Portable Individual Aerator V2 is an enhanced version of https://www.thingiverse.com/thing:4227395/files. Changes Include: * Reinforced strap attachments (slightly too fragile on Version 1) and case structure. * Improved design. * More compact, flat shape (reduced bulk). * Addition of a space compatible with a thick filter or folded in accordion. The filter can be changed without stopping the fan and without risk. No longer necessary to drill a hole for the power supply. For use as personal protective equipment (not responsible for assembly quality, materials, and internal filter), the plan for a positive pressure hood has been added. This allows for a portable aerator (placed in the back). Hood material options include medical kimgard, plastic film (90 micron minimum thickness), light waterproof fabric (parachute canvas), or gummed craft paper reinforced with adhesive (duck tape). The hood is reusable but should not be shared with another person due to hygiene concerns. If there's a significant air leak in the neck, it can be resolved by adding an elastic band around the neck and/or taping the bottom of the hood to clothing. Assembly Requires: * 4 steel bolts, 4-5 cm long and 4 mm in diameter (+ adapted bolts). Preferably flat-headed. * Glue suitable for 3D printing plastic (PLA: neoprene, cianoacrylate, epoxy contact glue, hot glue, or polyvinyl glue with quick setting). * 3 screws (wood or plaster) 2 cm long and 4.5 mm diameter. * A computer fan 8 cm by 8 cm and 2.6 cm or less thick. * A 12 V battery suitable for the fan (check the fan's amperage). For the Hood: * A semi-rigid transparent screen approximately 100 to 800 microns thick, made of PVC or another transparent plastic. * Duck Tape, glue suitable for fabric and plastic used.
