Face shield on a small printer (thermoforming)

LEGEND - JAMES WILSON has designed this mask. So, if you have a 3d printer, but its too small to print a face mask, james has solved this problem. This has been designed to print a full size face shield, on a print bed of 140x140x140.

To achieve this, its designed to be printed out of position. After printing, you dip it in boiling water and bend it into shape.

See the thermoforming video here. https://youtu.be/3pviuv_Iv_8

Thermoforming as per the video with boiling water, dip for no longer than 7 seconds.
Probably also need to warn them that boiling water is hot! So take care.
