thingiverse

Human: Still Work In Progress, probably too thin and fragile.\r\nUse only if exposure can't be avoided and proper equipment is unavailable.\r\nThis mask is NOT approved for any use by any agency, use at your own risk.\r\nWe've failed to find filter materials that block the banana scent used in fit-testing\r\nPrint the mask in PLA (no supports needed, raft doesn't matter)\r\nPrint the mask and cup separately (mask quality will degrade otherwise)\r\nPrinting in a light color helps see if the mask is flush with your skin\r\nDip the printed mask in hot water and form-fit it to your face, repeat as necessary\r\nPaint the mask to seal the tiny cracks present in all 3D prints\r\nYour skin must touch the mask in a continuous line around nose and mouth\r\nUse two rubber bands to secure the mask onto your face, more tension will help
