Update - FaceMaskV4 Reinforced joints Cleaner design Still 0.3mm layer height For 1mm nozzle you can print in spiral mode. A slight over extrusion is suggested (1.08) but not too much to close the slit. For 0.4mm nozzle print using 0% infill, no top or bottom layers, 0.5mm extrusion width, 2 perimeters, again a slight over extrusion (1.08).

Update - 1mmNozcliplessShieldV3 This is an update for those using 1mm nozzles. To be printed with 0.3mm layer height. Can be printed using vase mode. I set extrusion width to 1mm and then extrusion multiplier to 1.2 (I suggest playing with these 2 settings to get the slit in the front right and the walls bonding everywhere else).

New version Updated - FaceMaskCliplessV2

1. Increased slit from 0.2mm to 0.3mm.
2. Added wave profile in slit for increased clamping ability for a wider range of printers and settings.
3. Flanged open the slit top and bottom by 0.3mm to assist with inserting plastic and preventing elephant foot on first layer joining the slit.
4. Decreased text depth.
5. Opened up the sides for better comfort.

Face shield which clamps an A4 plastic shield without the need for clips.

Stacked version can be printed on a 0.3mm layer height but it recommended you reduce the layer height at the seams.

I am getting about 10 face shields per 13 hours per printer.
