This is my design of a Prusa hole spacing face shield. This prints much faster (18min on stock Anycubic i3 Mega) and many more (30) at once so less labour intensive then other designs.

Latest estimation of small groups spread around the UK is that we have collectively printed 50.000+ of this design now (5th May) with only about 50 guys.

Here’s my group in Southampton. https://www.gofundme.com/f/3d-printed-face-shields

Here’s a group in Wales. https://www.gofundme.com/f/1ytppbac1c

Holes in the clear plastic sheet need to be as per Prusa 80mm then 60mm in the middle section and 80mm again. Can do this with a simple 80mm hole punch.

They are all 5.2mm high so 10 pieces is 52mm etc.

The CE5 GCODE works really well on Ender 3, 5, 5pro.

The VIS GCODE on Anycubic Mega S.

May need 105% flow depending on filament.

Added few more files and see below stack tweaker to achieve better splitting for bigger nozzles (0.8-1.2mm).
