This is a remodeled version of the Protective Visor by Erik Cederberg (3D Verkstan). For the original model and instructions, visit their website.

I modified Erik Cederberg's excellent face shield file to fit on the Prusa Mini! Got a smaller printer? Ready to help hospitals in need? This mask prints in less than a half hour - or even sub-20 if you've got your settings dialed in.

The shield component is a US Letter size (8.5 x 11 in) transparency film, 3-hole punched twice. A small spacer is included to punch the holes at the right distance to fit the frame (unmodified from 3D Verkstan's original).

Print instructions

This model is optimized for printers with at least 160mm x 160mm x 5mm of build area. The mask fits identically to the original - the arms are shortened, but the general shape is unchanged.

If you'd like to print a few extra masks overnight, use one of the included stacked variants. Each file is named according to how many shields are stacked, and what the separation is between each shield (eg. 16x250 is 16 masks with a 0.250mm gap between each mask).

I made sure to include .3MF and .STL variants of the stacks, so feel free to experiment with different separation distances.

Happy printing, and stay safe out there!
