Designs available:

• Stacked: Prusa mask main part

• Stacked: Protective visor by 3dverkstan

• The A mask homologated in a hospital in Madrid (unfortunately I cannot recommend the design, simpler is better, so avoid this one)

  • Original B1 part
  • Stacked: B2 part

There is one empty layer between each part to allow an easy separation. Support material not needed.

Hay una capa vacía entre cada pieza, lo que permite separarlas fácilmente. No es necesario material de soporte.

Tested with this cura profile (see the result ). I suggest to first try with your own profile and layer height 0.3mm

Stacked with OpenScad software, the code is available in the "source_code" directory.
