Mask 3D NanoHack 2.0

thingiverse

Hello everyone. I made an improvement of this 2.0 mask: http://copper3d.com/hackthepandemic/ Improvements so far: 1. The mask is thicker and more durable 2. The elastic band can be locked in a holder 3. No support structure needed. (Print your mask without support) 4. Better airflow (I will add this feature in future) Edit: If you don't have a seal, you can print the rim with TPU (The rim is imported from copper 3d. It's not an efficient file. I'm on my way to make a flat rim. It's way easier to print) I printed with: Temperature: 200 Deg C Layer height: 0.2mm Speed: 50mm/s Bed: 60 Deg C Material: PLA The following text is recommended: Source if Online!: http://copper3d.com/hackthepandemic/ (Here you can find the original) CLAIMS ABOUT NANOHACK: The purpose of the NanoMask is to offer general population protection against airborne particles and prevent spread of liquid aerosols that could contaminate airways. It is not an N95 mask. It is a face mask and should not be considered as PPE. If you are healthcare professional, use it as last resort device: cannot manipulate airway such as intubation, mechanical ventilation, fiberoptic bronchoscopy and similar procedures. You can use it in common spaces. It should be used for maximum of 8 hours and change non-woven filter once a day. After handling active filter, you should wash hands and follow precautions as recommended by health authority. Nanohack is polymer based device, we recommend using PLACTIVE (PLA based material) for monoblock structure and MDflex (TPU based material) to print outer rim. With this setup, you can have comfortable mask with good seal. We understand that there may eventually be complex access to MDflex in some parts of the world. This is why we have released a version with integrated rim into monoblock structure. With this solution you can obtain a structure that fits properly but that must be complemented with some additional sealant and hypoallergenic cushioned tapes for nose and cheeks, especially if it is going to be used for long periods of time. Keep in mind also that if you leave elastic bands very tight it can hurt you, we don't want the use of Nanohack to be counterproductive or cause discomfort. The NanoHack was designed to fit a 12 cm height face very well, measured from tip of chin to ocular plane, a horizontal line that passes just between eyes, and distance between cheekbones (measured straight above nose) also 12 cm. We understand that all faces are different. If your face is smaller or larger than these measurements, we suggest rescaling the model by 5% or 10% so that there is perfect fit to your face.
