Support free Dave valve (covid oxygen mask)
thingiverse
I started from the amazing project https://www.isinnova.it/easy-covid19-eng/ that converts the Easybreath snorkeling mask into a breathing assistance mask for COVID-19 emergency (BUT NOT CERTIFIED).\r\n\r\nI simply drew in 3D a version of the second valve (called Dave) which can be printed without any support with FDM printers.\r\n\r\nI uploaded also the solid model in STEP format.
