I give a try to a strap band for the attach of the mask and it work perfectly !

Hi, as requested by @cotontigeh i tested the .STL (PRUSA face shield RC3) on a crealityCR10S.
Object seems OK as expected, i have an export of my configuration ready via prusa slicer available for anyone who need it.
Otherwise here some of my prints settings :
• Printing time : 4 hours 7 minutes for 1 shield
• Layer height 0.2mm
• 4 walls or perimeters
• 4 layers for TOP & BOTTOM
• 20% for infill with gyroïde pattern
• NO SUPPORTS
• Speed is : - 60mm/s for walls
- 30mm/s for external wall
- 20mm/s for solid infill
• Temperature is 200°c for my filament (Eryone filament PLA) and 60°c for bed temperature with cooling fan activated.

Still i do not recommend to use it for medical purpose since there is some cavities with FDM printers that could lead to contamination but i would give it to anyone exposed and in the need of protection at LYON.

That's really awesome.

Regarding the funding, we need:

  • One photo of the group wearing the masks (if they agree)
  • A signed letter from the hospital (to discharge responsibilities and proof for the grant)
